| Other humidity warning signs are: 1) water dripping off the OPLE building (or wet spots on the asphalt straight down from the eaves); 2) cold, clammy feel to metal objects such as railings; and 3) dew forming on the parked cars. It is important to note that the humidity can rise from 50% to 80% in as little as 10 minutes, so keep a close eye on the rate of change of the humidity plots. It can also rain or hail from small, passing clouds when the humidity is quite low, even 30% RH or lower. Operators have been surprised before by small puffy clouds in unsettled air with low humidity. If in doubt, stay closed. The HPWREN webcams are a good resource to view the bottoms of clouds. If there is any virga, the clouds are holding moisture and try to rain out. Stay closed if you see anything streaming below the clouds. | Other humidity warning signs are: 1) water dripping off the OPLE building (or wet spots on the asphalt straight down from the eaves); 2) cold, clammy feel to metal objects such as railings; and 3) dew forming on the parked cars.

| - | | + | The path of the IR light will be different from the visible light because of dispersion in the AO dichroic and atmospheric refraction. The starlight will also be offset from the blue beacon that is used for locking labAO. This offset will rotate on the sky as the telescope moves in azimuth. To compensate for this offset, we misalign the beacon flat mirror to center the IR light from the star on the Six Telescope Star Tracker (STST). |

| - | - WFS/TT tab, toward | + | SPICA uses MIRC-X as a fringe tracker and MYSTIC as a fringe finder. During SPICA observing runs, data are often collected on all three combiners simultaneously (SPICA, MIRC-X, and MYSTIC). A new alignment has been adopted for SPICA: |

| + | |||
| + | Therefore, we now have a uniformed alignment sequence for visible and IR combiners. | ||
| + | |||
| + | For Silmaril, NIRO will be transformed into an IR star tracker called Strider. If Strider is in use, then STST should be out of the beam. | ||
| + | |||
| + | For CLASSIC, it might be useful to align the star using STST so that the alignment into CLASSIC stays consistent between the calibrator and science target. However, check with the Observer to find out if they want to use STST. The faintest targets observed with CLASSIC are probably not visible on STST, so in these cases, it would be better to observe without STST in the beam. | ||
| + | |||
| + | With TipTilt now being performed at the telescope instead of in the lab, there is no longer a stable reference position for PAVO, and the star will often drift out of the PAVO mask holes over the course of an observation. If the PAVO stars are bright enough to see on STST in the IR, then it might be useful center the star on STST and turn on STST guiding. There will still be an offset between the IR and visible light, but after the visible light is aligned to PAVO using the PAVO optics, this strategy might stabilize the star position. Ask the PAVO observer whether they might want to use STST guiding in the IR. If not using STST, then skip the STST steps in the following sequence. | ||
| + | |||
| + | **Selecting a Bright Star for Initial STST Alignment** | ||
| + | |||
| + | Faint stars (H > 5 mag) will not be easily visible in STST. Therefore, before slewing to the first star of the night or when slewing to a different region of the sky, slew to to a nearby bright IR star to align the beacon flat and set the beacon box offset on the TWFS. Then slew to faint star, keeping the red beacon at the same fixed position. | ||

| + | ==== Trouble Shooting - AO Performance - Obsolete ==== | ||
| + | |||
| + | If AO performance is bad try these steps in the following order: | ||
| + | |||
| + | * Check aberration plots. If X/Y terms are not going to zero, try stopping servo loops, recentering alignment, and turning back on servo loops. | ||
| + | * Turn off the blue beacon and check the centering of the star on the ACQ hole. Adjust box positions to center star (ADJ popup on obsgtk). Hint - zoom in on ACQ display. | ||
| + | * Look at red beacon on tel WFS and try zeroing the centroids using ZCEN on obsgtk. Note if you are using IR combiner, then align red beacon to blue starlight boxes (not the offset green beacon boxes) before clicking ZCEN. Align beacon back to STST reference after. | ||
| + | * Check alignment of blue/red beacon on labao - make sure they are aligned properly with labao boxes. Use red beacon to find center of pattern then turn on blue to be sure the spots are in correct boxes. If not, move M7 to center with correct boxes. Note that the blue/red beacons are offset by about half a box. | ||
| + | * If IR flux is low or spots are maps are poor on MIRCX/ | ||
| + | * Go back to stow and check the full beacon/ | ||
| + | * If X/Y and higher order terms are still not going to zero after checking alignment, making a new flat, and zeroing centroids, then this likely means a new reconstructor needs to be made. Notify charatech (maybe try taking onsky reconstructor). | ||
| + | |||
| + | |||
| + | ==== Trouble Shooting - Locking TT and AO Loops - Obsolete ==== | ||
| + | |||
| + | - If **not locking**, make sure red beacon is off, make sure on blue boxes, load def flat or last flat, make sure no clouds | ||
| + | - If **not locking**, make sure DM current is low or around 1.2 | ||
| + | - If not, Obsgtk, main tab, LD DEF | ||
| + | - If **drifting** | ||
| + | - Unlock TT DM, last flat, make drk, next, lock again, TT | ||
| + | - DM sometimes makes it hard to hold on to star if using flat. | ||
| + | - if star is **flaring** | ||
| + | - lower the gain, may need to go lower than 100, maybe even 30 or lower. Lower until star is no longer flaring and spot is compact. | ||
| + | - May also need to change to higher gain for dimmer stars, Vmag 8 or higher | ||
| + | - Select [FAINT], wait til wfs starts moving, relock TT DM. | ||
| + | - After TT DM, Zdark if gain is not 300 | ||

| + | |||
| + | If the starlight is missing from the boxes on the TWFS on S2, you might be able to improve performance on by applying a threshold to ignore the TWFS boxes without flux This is likely caused by an alignment problem at the telescope/ | ||
| + | |||
| + | - If light is missing in some of the TWFS boxes, set a threshold to ignore those boxes. | ||
| + | - Open: **wfs_gtk S2** | ||
| + | - The threshold is set on the WFS/TT tab. Enter a number in the box to the left of the **THRESHLD** | ||
| + | - A threshold of 0.5 to 1.0 seems to work well. | ||
| + | - Look at DM tab to make sure the edge actuators are not at or close to 1. If they are, try iterating between the default flat and new sky flat so that the edge values are not saturated. | ||
| + | - The thresholding is based on the standard deviation across the full frame (with starlight). The statistics might be better if you make a dark for the WFS. Note that darks should be made after the sky is fully dark, otherwise the dark will include residual sky light. | ||

| + | ==== Locking on a Target ==== | ||
| + | |||
| + | Locking on a star involves aligning the beacons, locking the star on tiptilt and tel AO, and locking the blue beacon on labAO. TelAO performs fast correction to compensate for atmospheric turbulence. LabAO performs slow correction to compensate for non-common path length errors along the beam path from the telescope to the lab. | ||
| + | |||
| + | The path of the visible and IR light into the lab is different because of atmospheric refraction and dispersion in the AO dichroic. Below we outline alignment steps separately for visible and IR combiners. For IR combiners we use the Six Telescope Star Tracker to align the IR light in the lab. | ||
| + | |||
| + | While tracking on a star, labao will offload X,Y tilt to M7 to keep the the blue beacon centroids aligned to labAO WFS. There are two methods for doing this: | ||
| + | |||
| + | **Old method**: DMTILT is gray (reconstructor ignores tilt). **M7AUTO** | ||
| + | |||
| + | **New method**: **DMTILT** | ||
| + | |||
| + | **STOP A: **If needed, the 3 STOP A buttons on obsgtk will stop any alignment sequences in progress. | ||

| - | ===== The Next Slew - Avoid Limit Switch Issues Near AZ 0º: ===== | + | ===== Guiding with STST ===== |
| + | |||
| + | For stars that are bright enough to see on STST, we can actively guide to keep the IR flux centered in the lab. This will minimize the number of fiber maps that are needed to keep the light centered on mircx/ | ||
| + | |||
| + | There are three methods for keeping starlight aligned on STST: | ||
| + | |||
| + | * **STST ALIGN**: The [STST] button on obsgtk takes the star offset (delX, delY) from STST and applies it to the BEACON-FLAT and M7 in a single move (open loop). During this operation, the auto-guiding of M7 is turned off to avoid conflicts. This command is very fast, a few seconds. | ||
| + | * **STST GUIDIN****G using obsgtk**: The [GUIDE] button on obsgtk is a continuously running background process that runs every 10 seconds. It takes the star offset from STST and moves the BEACON-FLAT in small increments of 400 units. This method relies on the Labao M7 auto-guiding corrections against the BEACON-FLAT moves (closed loop). This mode added more short-term variations to the flux trend plots because of backlash/ | ||
| + | * **STST GUIDING using ststrtd_gtk**: | ||
| + | Follow this procedure to use active guiding with STST: | ||
| + | |||
| + | * <font inherit/ | ||
| + | * After the star is centered on STST, click the boxes next to the active scope (S1 S2 E1 E2 W1 W2) and turn on the **[GUIDING]** | ||
| + | * The STST-LABAO-BOXES guiding will correct errors above 5 pixels and any slow beam drift. | ||
| + | * If the LABAO boxes move too much, the LABAO reconstructor can have problems (tests show that it can remain stable for over 30 minutes). If you see flux dropping on mircx/ | ||

| + | |||
| + | |||
| + | ===== Guiding with STST ===== | ||
| + | |||
| + | For stars that are bright enough to see on STST, we can actively guide to keep the IR flux centered in the lab. This will minimize the number of fiber maps that are needed to keep the light centered on mircx/ | ||
| + | |||
| + | There are three methods for keeping starlight aligned on STST: | ||
| + | |||
| + | * **STST ALIGN**: The [STST] button on obsgtk takes the star offset (delX, delY) from STST and applies it to the BEACON-FLAT and M7 in a single move (open loop). During this operation, the auto-guiding of M7 is turned off to avoid conflicts. This command is very fast, a few seconds. | ||
| + | * **STST GUIDIN****G using obsgtk**: The [GUIDE] button on obsgtk is a continuously running background process that runs every 10 seconds. It takes the star offset from STST and moves the BEACON-FLAT in small increments of 400 units. This method relies on the Labao M7 auto-guiding corrections against the BEACON-FLAT moves (closed loop). This mode added more short-term variations to the flux trend plots because of backlash/ | ||
| + | * **STST GUIDING using ststrtd_gtk**: | ||
| + | Follow this procedure to use active guiding with STST: | ||
| + | |||
| + | * <font inherit/ | ||
| + | * After the star is centered on STST, click the boxes next to the active scope (S1 S2 E1 E2 W1 W2) and turn on the **[GUIDING]** | ||
| + | * The STST-LABAO-BOXES guiding will correct errors above 5 pixels and any slow beam drift. | ||
| + | * If the LABAO boxes move too much, the LABAO reconstructor can have problems (tests show that it can remain stable for over 30 minutes). If you see flux dropping on mircx/ | ||
| + | * **IMPORTANT: | ||
| + | ===== The Next Slew - Avoid Triggering AZ Limit Switches: ===== | ||
| + | |||
| + | Always pay attention to the AZ you are slewing from or to, to avoid passing the sensors incorrectly and dealing with scopes getting stuck near 90° or 270°. | ||
| + | |||
| + | __Az Limit Switch Near 0º:__ | ||
| + | |||
| + | There are two sensors negative and positive near AZ 0. | ||
| + | |||
| + | It is okay to slew completely past AZ 0 in either direction. | ||
| + | |||
| + | However, if you slew close to zero from the west or away from zero to the east, it is possible you will hit just one sensor. | ||
| + | |||
| + | * If your next slew is continuing past zero in the SAME direction that you came from, both switches will get hit, and all is fine. | ||
| + | * If your next slew is going back away from zero, you will not hit the second limit switch and will run into problems later. | ||
| + | * before going to your next slew away from zero, slew to a different star past zero to hit the second limit switch. | ||
| + | * can use obsgtk,** [F**i**nd *]** | ||
| + | * Az: ~355 or 5º, keep el the same, mag 6 | ||
| + | * now you can slew back the other way to the next target. | ||
| + | |||
| + | If you don't pay attention and only hit one sensor at AZ 0, some or all telescopes will continue to stall near 90 or 270 degrees and it is a pain to fix. Will have to trip the limit switch at the telescope. | ||
| + | |||
| + | __TCS Az limit beyond -90 and 450º: __ | ||
| + | |||
| + | On the telescope server, keep an eye on the TCS az to not go beyond -90º and 450º. If you are getting close, telescopes will have to go the other way around to avoid hitting the limit. | ||
| + | |||
| + | * can send to STOW or to another star using FIND* on obsgtk. | ||
| + | |||
| + | Got to [[: | ||
| + | |||
| + | ===== Additional Observing Procedures ===== | ||
| + | |||
| + | ==== Manually Slewing a Telescope: ==== | ||
| + | |||
| + | If you need to send a telescope to a different star while keeping the others at their current position: | ||
| + | |||
| + | * scope server, type in the star name (use a space instead of an underscore), | ||
| + | * Obsgtk, Control tab, Dome section, press [ON] to the left of AUTO]. | ||
| + | |||
| + | ==== Initialize pointing ==== | ||
| + | |||
| + | Initialize the pointing of the telescopes on your first target by going to the MAIN tab on the obsgtk and clicking the red [INIT] button. Make sure you are on the correct star before initing the scopes or you will have problems. This may have to be repeated if the pointing drifts during the night. This will allow more consistent and accurate pointing for this part of the sky. You can also INIT during the SKY frames on MIRCX and MYSTIC since the star is in a good spot for finishing a slew. | ||
| + | |||
| + | ==== Data Acquired ==== | ||
| + | |||
| + | - Mircx/ | ||
| + | - CD, Control tab, Data Acquired after shutter sequence | ||
| + | - Make sure combiner(s) are selected or you won't get combiner in data entry for the log | ||
| + | |||
| + | or | ||
| + | |||
| + | - Hit reopen on CD after data sequence/ | ||
| + | - Sometimes data acquired will show after shutter sequence finishes | ||
| + | |||
| + | ==== Monitoring MIRCX/ | ||
| + | |||
| + | When running MIRCX/ | ||
| + | |||
| + | ==== Adjusting ACQ Camera Settings at dusk and dawn ==== | ||
| + | |||
| + | - When it is light out, can lower the exposure to make ACQ darker | ||
| + | - Adjust tab, exp down. | ||
| + | |||
| + | ==== Acquisition Laser Alignment if the star does not lock in Tiptilt (Rarely used) ==== | ||
| + | |||
| + | - Set VISBEAMS to correct beams. | ||
| + | - Laser Filter on ND 3.0 | ||
| + | - If the beacon and fiber covers are open, use the SHUTTERS GUI to open the laser shutter and the corresponding B1-B6 shutters. | ||
| + | - You can also put in the corner cube with the [CCIN] button. | ||
| + | - You will see at least two stars and two laser spots in the ACQ window. There is a reflection, hence two images of each. The desired spots are the right ones. | ||
| + | - Use the “ORIGIN” paddle on the ADJUST Tab of the Telescope GUI or obsgtk to align the TV cross-hairs to coincide with the laser spot. | ||
| + | - Close the laser shutter and the B1-B6 shutters. | ||
| + | - * Move the corner cube out with the [CCOUT] button on the Main tab or Control tab on the telescope gui if you used it. | ||
| + | - It will take about 10 seconds to move out of the the beam. | ||
| + | - Hit [MOVE] under the TV tracking menu on the Main Tab of the Telescope GUI and then click the right star to bring the star to the cross-hairs. | ||
| + | - If it doesn' | ||
| + | - Lock Tiptilt as shown above. Maintain the ACQ laser alignment during the night by adjusting the crosshairs to the star after locking Tiptilt. | ||
| + | |||
| + | ==== Changing Ref Cart position: ==== | ||
| + | |||
| + | - Manually | ||
| + | - Take difference of the Targets pos and Laser position for cart farthest to the back (~44.2 m) or closest to the front (-1.2 m) | ||
| + | - If w1 is close to front also, adjust w1, then the next farthest one. | ||
| + | - Then make up the difference on the ref | ||
| + | - Opt Delay (check for ref cart pos) | ||
| + | - Wait like 5 seconds after star acq, CD, Opt Delay, | ||
| + | - WHEN plot gives starting and ending ref cart position. May not be correct for S1 as ref. | ||
| + | - If W2 get's dropped from observations but is the ref cart (ex. going from 6T to 5T with no W2): | ||
| + | - keep W2 in the config | ||
| + | - turn cart off when its near the back | ||
| + | - set ref between 44-70 to get delay on other carts. | ||
| + | |||
| + | ==== POP changes later in the night ==== | ||
| + | |||
| + | - Once shutters are finished, let carts know where to go | ||
| + | - CD → Main tab, Data Acquired → slew to new sci/cal | ||
| + | - Obsgtk → M7Auto | ||
| + | - Change configuration to new pops, send | ||
| + | - Make sure ople reads new star | ||
| + | - Star acquired | ||
| + | - Do pop changes | ||
| + | - Obsgtk, Control, **[On]**, M5targ, close M5 | ||
| + | - Shutters, Turn on laser, open vis shutters for beams, | ||
| + | - If using SPICA, do [SPICA PERI OUT] to see laser. Reopen on shutters gui if it gives an error message. | ||
| + | - Visbeams, go to beams you want, Laser filters, ND 0.3 or OPEN | ||
| + | - Popperi, turn on power to pops you want to change, change first pop | ||
| + | - turn off pop when it finishes on popperi | ||
| + | - Align pop on obsgtk | ||
| + | - While aligning one pop, start the other | ||
| + | - When finished aligning, open M5, ACQ | ||
| + | - Turn off Laser, close beam shutters, | ||
| + | - If using SPICA, do [SPICA PERI IN] | ||
| + | - If staying on the same star, turn off labao servo and load the default flat first. | ||
| + | |||
| + | ==== Changing Beam Configuration During the Night ==== | ||
| + | |||
| + | If you need to realign the lab dichroic or the IR mirror on the beam sampler stage during the night, make sure to remove STST stage (using the shutter gtk) before doing any alignments. Put STST back in the path after you are finished with the lab alignments and are ready to go on back on sky. | ||
| + | |||
| + | STST gets the beam information from the telemetry server. Try clicking RECONNECT button on ststrtd_gtk. Also try resending the updated configuration from Cosmic Debris and the OPLE GTK (yes try both!). If that doesn' | ||
| + | |||
| + | * killall telemetry_server | ||
| + | * bootlaunch_master | ||
| + | |||
| + | Reopen Cosmic Debris and resend configuration again. If that doesn' | ||
| + | |||
| + | ==== Locking Lab Tiptilt (only used in special cases) ==== | ||
| + | |||
| + | With the star aligned with the acquisition ticks, check to make sure there are counts on the TipTilt server or the white plots in the TT windows have condensed. | ||
| + | |||
| + | - Obsgtk, Main Tab, [TIP/TILT] under the Pointing Servo menu. | ||
| + | - If this button is not pressed, then the green dots on the tiptilt windows will drift and eventually drop TT lock. | ||
| + | - The [STAR ACQUIRED] button on Cosmic Debris also starts the Tiptilt servo for all active scopes with one push of a button. | ||
| + | - On the Tiptilt Servo Control GUI, turn tiptilt [ON] for each telescope or use the [TT ON] button on Cosmic Debris to perform this function for all active scopes. | ||
| + | |||
| + | ===== Procedure for Shutting Down at the End of the Night ===== | ||
| + | |||
| + | ==== End Night Sequence ==== | ||
| + | |||
| + | The End Night sequence on Cosmic Debris can be used to end observing and stow the telescopes, carts, and domes and close the mirror covers. It will only stow the active scopes, carts, and domes, so if there are other scopes open, make them active in the Configure tab of CD or stow them manually with the procedure below. | ||
| + | |||
| + | - Cosmic Debris, **[REOPEN]**, | ||
| + | - Automatically: | ||
| + | - Stops twfs cameras and closes shutters | ||
| + | - Stow active telescopes | ||
| + | - Close M1 (primary) and M3 mirror covers, | ||
| + | - Send the active OPLE carts to the back switch | ||
| + | - Close the OPLE socket | ||
| + | - Archive the accumulated data for the night. | ||
| + | - Does **NOT**: | ||
| + | - close the dome slits | ||
| + | - send inactive scopes or carts back. | ||
| + | - Update the configuration with any inactive scopes to make sure those carts can be sent back manually as well. | ||
| + | - Doesn' | ||
| + | - Doesn' | ||
| + | - Wait for CD to say end night sequence is complete. | ||
| + | - Obsgtk, CONTROL→ close M7 and M5, FINDER (if used). | ||
| + | - Obsgtk, MAIN→ TWFS Gain 100, [USBOFF], Labao [STOP], [OFF] | ||
| + | - Obsgtk, CONTROL→ turn off Red, Fiber, Beacon. | ||
| + | - Beacon Laser Control → Turn off red and blue beacons | ||
| + | - Obsgtk, WFS → SHUTTERS OFF, DM POWER OFF | ||
| + | - Never do camerlink off | ||
| + | - Only do COOLING OFF when notified by daytime staff (e.g., during hot summer months) otherwise keep it on. | ||
| + | - Shutdown STST | ||
| + | - Click “Start Camera” and "Start RTD" button to turn off the camera (the button will go from green to gray). | ||
| + | - Change the filter wheel to the closed position. | ||
| + | - Shutter gtk, remove the STST stage from the beams. | ||
| + | - Reopen if needed to get stage to show it is moving out. | ||
| + | - For now, the daytime alignment is done without STST in the path so it is important to remove STST at the end of the night. | ||
| + | - Confirm all telescopes are at stow before disabling and turning powers off. | ||
| + | - obsgtk → main tab, [DISABLE] for all scopes | ||
| + | - Power GUI | ||
| + | - Turn off the power for [TEL AZ], [TEL EL] and [TIP/TILT] for all scopes once stowed | ||
| + | - Close slits after M1 fully closes (ON, SPY 2 to check). | ||
| + | - Visually check all telescopes in the spycams 1&2 to make sure all covers and slits are closed. | ||
| + | - make sure finder lid closed all the way (sometimes doesn' | ||
| + | - Obsgtk → Turn the TV [OFF] | ||
| + | - Leave the telescope GUIs open until the End Night Sequence is finished. (Cosmic Debris will turn on the TVs and the Spy Cam 2 during the End Night Sequence.) | ||
| + | - Ople server →Double check carts are at the backswitch, once they are, Ople GUI, [OFF], close ople server | ||
| + | - Shut down the ople control system | ||
| + | - Close ople server | ||
| + | - Press the shutdown button on the OPLE System Control gui, wait until all 6 dots are grey. | ||
| + | - Press the Metro button, and wait until it is grey. | ||
| + | - Close the gui on Wazoo. | ||
| + | - Turn off the metrology laser (METLAS → Laser Power) | ||
| + | - Close labao servers | ||
| + | - If using Classic or CLIMB: | ||
| + | - Check to make sure the dither is off by looking at the dither status in the CLASSIC/ | ||
| + | - If necessary, this can be turned off from the dither tab on the Classic/ | ||
| + | - Turn off [NIRO CPU], and [CLS-DITH], on the POWER gui. | ||
| + | - Close CLIMB/ | ||
| + | - Leave GPS, Metrol, and Vacmon servers and the Telescope servers open and running | ||
| + | - On Cosmic Debris, click **[REPORT]** | ||
| + | - On the Report, add the Observers and Baselines entries, add positive comments to the bottom of the report and put your name at the end. | ||
| + | - Cut and paste this into an email to CHARA Obs and send it. | ||
| + | - To archive the report, you must also hit the **[Email]** | ||
| + | - You can close Cosmic Debris after you have sent out the Observing Report. | ||
| + | |||
| + | ==== End Night Tech Report ==== | ||
| + | |||
| + | At the end of the night, write a tech report detailing any issues that happened throughout the night. Helpful to keep an open email draft to note issues as they happen instead of waiting until the end of the night to write everything down. | ||
| + | |||
| + | - Include as much detail as possible (i.e. what did you try, did it work/not work, az/el if there was a scope issue, etc.) | ||
| + | - If a problem keeps happening (ex. cart keeps getting stuck at the same location), keep mentioning it in the tech report until it gets fixed. | ||
| + | - Add your name at the end and send to charatech. | ||
| + | |||
| + | ==== Manually stowing the telescopes ==== | ||
| + | |||
| + | - Unlock the tiptilt and AO loops. | ||
| + | - Obsgtk, → SPY1 | ||
| + | - Control Tab, →[STOW]. | ||
| + | - When the telescopes reach an elevation above 50 degrees, you can begin closing the mirror covers (one at a time, click each button only once). | ||
| + | - M1 CLOSE, | ||
| + | - M3 CLOSE, | ||
| + | - M5 CLOSE, | ||
| + | - M7 CLOSE, | ||
| + | - W1, W2, and S2 M7 covers often read MOVING, don't click them again | ||
| + | - Finder CLOSE | ||
| + | - W2 and E1 finder covers need a second click to close | ||
| + | - Use SPY2 to make sure mirror covers close properly. | ||
