-Lab booties/shoe covers must be worn by all. Throw out booties that have holes in them. The traction tape on the steps are particularly rough on booties so examine them before and after using them. Proper clothing is also important. Loose hanging jackets or garments can snag on mirrors or other exposed equipment and are better left outside of the lab. Please be alert and move slowly and cautiously. When entering the lab make sure to walk across the sticky floor mat. If the mat isn’t sticky, remove the top layer. If this is close to the final layer please notify the staff. No more than three people are allowed in the lab at once unless it is 3 to 4 hours before observing time or there is some pressing need. Many bodies can create unwanted atmospheric effects. With too many people, it is too easy to bump into each other and the equipment. If you bump, hit, move or just tap anything in the slightest way, let us know. Never touch anything you have not been trained to use. If ever in any doubt, leave it alone and get someone who knows. Any unusual sounds, sights, movement of equipment, etc., should be noted. You must know the path of the laser beams, metrology or alignment. Stay out of their way especially right before observing. If you must go into the lab during this time don’t forget to put on IR-protective goggles. Access and use of the lab requires training. If a piece of equipment does not appear to be operating properly let us know immediately. Also if you are uncertain about a lab procedure or a step in the alignment sequence contact us before proceeding. When leaving the lab any time of the day, remember to turn off all lights (fluorescent and incandescent). Lights left on generate unnecessary heat in the lab.\\+Lab booties/shoe covers must be worn by all. Throw out booties that have holes in them.

Inform Larry or Craig if the oil temp is low and the heaters did not run to bring the temp up before starting.\\ 
-Go into lab building, check pressures on Vacmon display. If pressure is higher than 100 torr in any of the lines, pump those lines only one at a time. Open valve a little, then come back to open fully. When all lines to be used are well below 100 torr, open all those valves. The final pressure should be 0.5 - 1.0 Torr in each line. The pump will normally bring all 6 lines down to .2-.3 Torr. The S1 and S2 lines leak the most during the day and will read the highest in the afternoon when you return, usually around 10 and 20 Torr. Note any unusual vacuum readings as they can indicate a leak beyond what is normal. Sometimes a line isn't pumped down the night before and can read higher than 30 Torr. Pump the highest ones down first as stated above.+Go into lab building, check pressures on Vacmon display.

 3.8 Synchronizing the clocks 3.8 Synchronizing the clocks
Line 211: Line 225:
 Synchronizing the clocks is very important for positional calculations of the telescopes and ople carts. All clocks are synchronized with the [SYNC CLOCKS] button on Cosmic Debris. Push the button, and after 17 seconds, a series of messages will display on CD to indicate that the various systems and servers are sync'ed. Check the OPLE server to confirm that the OPLE Tm clock is the same as CHARA time and that the error in the parentheses is (0) or (1). A reading of (0) and (-1) may cause problems as the clock is synced one second off from usual. Use [SYNC CLOCKS] again to get the OPLE errors to (0) or (1). A reading of a different time with (!!) behind it means the clocks have not been synced. Synchronizing the clocks is very important for positional calculations of the telescopes and ople carts.

It consists of opening the proper mirrorbeacon and fiber coversturning on the LED'and tel WFS cameras and labao displaysand aligning and focusing the red and blue LED's to the respective boxes on the tel WFS and labao.
  
-3.10+In the WFS tab of the telescope GUI or the CONTROL tab of the obsgtk, turn on the red and blue LED’s, open the fiber covers, then beacon flat coversThe CAMERALINK and WFS server are now part of Bootlaunch script and the ANDOR camera power should always be on in the POWER gui. Open M5 and M7 covers. 
 + 
 +In the WFS GUI or obsgtk, turn the cooler on (COOL ON) and open the camera shutter (SOPEN) or SHUTTER (OPEN/CLOSE), then CameraLink on (CL ON) if it is off, Camera on (CAM ON), and start TWFS display (MOVIE). For the scopes with DMs, use the POWER ON button on the WFS GUI (WFS/AO tab) to power the DM on, make sure that the DM current and temperature are displaying numbers. Press LAST FLAT to make sure that the last sky flat is loaded. If for some reason that flat is not good, going back to DEF FLAT will load the original default flat from the lab 
 + 
 +Turn on the ACQ camera in the obsgtk. Make sure that the red beacon is going through the hole in the acquisition display. If not, use Beacon UP/DOWN etc buttons on a HUT gui or WFS tab on the obsgtk to move it into the hole. Look for spots to be in boxes on the WFS display. Turn on the boxes on the obsgtk (NOBOX) to see how the alignment is. The boxes may be in the default position or may be moved to a position that worked better when observing. Align to whichever gives a more even illumination of spots in the boxes. As the red beacon is bright, use low gains, ie. 30-50 for the BARE dichroic or 200 for the IR dichroic, to make these alignments. If the red beacon spots on the WFS display are in the boxes, press (ALIGN BEACON) on the ALIGN tab on the TWFS GUI or (ALIGN) TELWFS: on the obsgtk, wait for completion. The default maximum number of tries is 10 so if it is not aligned before it ends, repeat the step if needed. 
 + 
 +Turn labao camera (ON) and (START) the display. Make a dark with the MKDRK button in the LABAO section of the obsgtk. Turn on the blue beacon. The blue beacon should show spots on the LABAO display. Adjust the FPS lower if they are dim. If the spots are not in the boxes, set the M7 mirror to the default position, then use the DICHROIC buttons on the WFS tab of the telescope gui, obsgtk or HUT gtk to get them in the boxes before using the auto align of the labao. If the spots are inside the boxes, then press (SCOPE DICH) button in the ALIGN tab on the LABAO GUI or the (ALIGN) LABAO: on the obsgtk to align the spots. 
 + 
 +If the spots do not show at all in the labao, the scope dichroic is likely out of alignment. Turn on the lab laser and set it to ND 4.0. Use the Dichroic controls to make the laser spots match the blue beacon spots on the ACQ camera view. If they are way off or not visible in the ACQ, you can hit the button for the appropriate dichroic in the HUT gui and it will set the dichroic to its last saved default position. 
 + 
 +Note the focus term on both the TWFS and LABAO GUIs or obsgtks. The next steps will minimize both focus terms. Start with the (BEACON FOC) button on the ALIGN tab of the LABAO GUI or (FOCUS) LABAO: on obsgtk, wait until the procedure finishes. Then use the (FOCUS WFS) button on the ALIGN tab of the TWFS GUI or (FOCUS) TELWFS: on the obsgtk and wait for completion. Note that focusing the beacons does not work when the spots are not reasonably centered. Always get the spots well into the boxes first before focusing. Sometimes it helps to repeat the scope dichroic alignment and focus as each needs the other to be close to align well.

-Only open the telescopes if the humidity is steady or dropping, at 75% or below. If the roofs outside the control room are ever dripping, then the telescopes should not be opened or should be closed immediately. If when starting out, the RH is above 80%, do not open unless it drops to below 75% and stays there for at least 30 minutes. If you do open after that, be wary and watch the RH, and if it starts rising, be prepared to close. Closing up takes about 5 minutes, so be ready for that. The array operator is in charge of protecting the telescopes and makes the final decision on whether the conditions are safe to open. If the RH is low at the beginning of the night, and rises after you are already open, the array operator should inform the PI around 70-75%, and start closing between 80-85%. 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 please 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 40% RH or lower.

-You can begin opening the telescope domes and enclosures about an hour or two before sunset. This will help air out the domes and improve seeing at the start of the night. Hot days benefit from an earlier opening to allow the scopes to cool. Before opening the domes make sure to check the current weather conditions and the forecast to make sure conditions are safe to open and are likely to be stable as you wait for it to get dark. Also confirm that Judit or Robert have finished the alignments in the lab as opening the domes will not allow the completion of the beacon alignments. Call the computer room at #424 if you do not see either of them. Monitor the progress of opening the domes by turning the televisions [ON] using the telescope GUIs. Click [SPY1] to view the dome slit. In the summer, when the sun is higher overhead, use the Dome GUI for each telescope to position the domes in the anti-sun position using the RA/DEC tab and the ANTI-SUN setting for AUTODOME. This will position the dome slit opposite the sun so that you can open the slit well before sunset. You may also go to the Dome Tab on the Dome GUI, enter 100 in the text box on the right, and press [GOTO]. This will move the dome slit to the east.

-It is typically dark enough to lock on your first star if TT reports ~ 1000 counts while not point at anything (sky counts) with the SpyCams turned off. This is roughly around 20 minutes after sunset or the time of twilight reported by Cosmic Debris. Here are instructions for slewing to a target and initializing the telescopes on a bright star at the start of the night: You may want to find a bright star near your first target to check the pointing of the telescopes and to do sky flats for the telescope DM's. The [FIND STAR] button on the MAIN tab of the obsgtk is useful in finding a suitable, bright star. It will report the star name, mag, and ALT and AZ in the text window at the bottom of the gui. There is also a printed list of bright stars in order of RA in the binder on the left side of the control room desk. If your first target is bright, then you may slew to it first. Enter the HD number of the star into Cosmic Debris using the Object or Calibrator Tabs. Click the [HD] button to register the entry. (Alternatively, you could enter a CHARA NUM, IRC, HR, HD, or SAO number and click the corresponding button.) If a star or new target is not recognized by Cosmic Debris, [[:chara:trouble_shooting#adding_or_finding_a_star_in_the_chara_database|follow the procedure below for DBADD]]. Check to make sure that EL/AZ reported by Cosmic Debris are correct and safe for pointing (never point below 15-20 degrees elevation). It is recommended to initialize the telescopes on a target between 40-70 degrees elevation. Hit the WHEN button for your first star to see a plot of cart positions and when it is in delay. Enter the ideal reference cart position into the REF text window on the Cosmic Debris Control Tab. Click the [REF] button to send the reference cart position to OPLE. Slew to your first star by clicking [OBJECT], [CHECK STAR], [CALIBRATOR 1], or [CALIBRATOR 2] on Cosmic Debris (depending on which field you entered the target information). Note that these buttons will slew the telescopes AND send the carts to their positions. Verify that the telescopes are moving by checking the azimuth and elevation status in the telescope servers (the left set of numbers show the commanded EL/AZ of the target while the right set of numbers show the current location of the telescope). Also view "SPY1" to check that the telescopes and domes are moving. If the domes do not rotate, click the AUTODOME ON button to enable the domes. The telescopes will usually arrive at the elevation of the target first and then continue in azimuth until the star appears in the finder or ACQ window. If the scopes do not move, check that they are enabled. The telescope server will show RA and DEC coordinates if enabled and will show DISABLED if disabled. The update in the OPLE server will take about 20 seconds for all the carts to get the new metrology calculation. Make sure all carts are tracking to values between 0 and 44m. You might have to click [TRACK] for the reference cart on the OPLE Control Tab. The [OL] buttons should be depressed gray for ALL active scopes (including the reference cart). The [MAN] buttons should be depressed gray for the moving carts to allow the beam combiners to send manual offsets to the carts. (The [MAN] button for the reference cart should be green.) When the telescope slew finishes, check the SPY 1 to make sure that the domes are aligned with the telescope. In the ACQ window, 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 the star is not in the ACQ window, go to the FIND window and do the same, then return to the ACQ window and repeat. If beacon alignments and sky flats are neededdo not center the star until the alignments are done first.+It is typically dark enough to lock on your first star roughly 25 minutes after sunset or the time of twilight reported by Cosmic Debris.

 The Job Queue ends with slewing to the star. The stars are acquired manually. Click [Star Acquired] on the Control Tab on Cosmic Debris to update the target information listed at the top of the Cosmic Debris window. This also turns on all the telescope TT servos, the same function as the TIPTILT button on each telescope gui. 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 now point to your first science target, calibrator, alignment star or fringe finder and begin the alignment sequence for the beam combiner and then start searching for fringes. The Job Queue ends with slewing to the star.

 +When running MIRCX/MYSTIC, the operator may want to have the windows open to follow the fiber mapping, scanning for fringes and data recording. The windows can be opened with the command mircx_launch_all_guis on a desktop terminal. It will open 5 windows for each combiner, but they do not need to all be open. Close what you don't want to monitor. The fiberexplorer, gdt, rtd, and super_gtk windows are most helpful.
