- | * Lab booties/ | + | |
- | * 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 until you are finished. | + | |
- | * 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. Besides, 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. | + | |

- | ==== Preparations in the Lab Prior to Observing ==== | + | 27 AUG 2012 by Judit, Current version 10 Aug 2021 by Chris |
- | | + | These are routine tasks to be performed in and around the lab every evening to prepare the array for regular observations. |

- | Go into vacuum pump shack | + | Go into vacuum pump shack. Flip on power switch for pump and wait for the blower to go on in about 6 seconds. Open the valve slowly (parallel to pipe means open) Note if fan cords are plugged into wall outlet to keep pumps cool in the summer. Note oil temperature when you start up. Oil temps below 15º C make for a labored start. There is currently a block heater on the north side of the pump and a space heater on the south side. 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 between 20-30 Torr in the summer and 15-25 Torr in the winter. 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 down the highest ones first as stated above. | ||

+ | === Going on Sky === | ||
- | ==== Going on Sky ==== | + | 5.1 Opening the Telescope Domes and enclosures\\ |
+ | \\ | ||
+ | You can begin opening the telescope domes and enclosures at least two hours before sunset. The white board has times written down that the domes can be fully opened. This happens when the sun is below 35º. Before this time, the domes can be vented by partially opening them. 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 Robert or Narsi have finished the alignments in the lab or the control room as opening the domes may interupt their 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 vent or open the slit well before sunset. You may also go to the Dome Tab on the Dome GUI, manually enter an anti-sun azimuth value from 70º-110º in the text box on the right, and press [GOTO]. This will move the dome slit to the east and opposite the sun. When the domes are facing east (and all lab alignments, dichroic changes or coude alignments are finished), click [UNL SL] and [SLIT] on the Control Tab of the obsgtk GUI to open the dome slit fully. If opening very early, use [UNL SL] and [VENT] to open it halfway. Be sure to open them fully when the sun has reached 35º for maximum cooling. | ||
- | \\ | + | Opening the M5 mirror cover also helps to cool the AO box by allowing the warm air to rise out of the box and cooler air to flow in from below the telescope. It can be opened early while doing the alignments in the lab. |

- | === 5.2 Opening | + | 5.4 Turn on the telescope |
+ | \\ | ||
+ | Make sure the telescopes being used are in their stow positions. For each telescope, the elevation should be at or near 90 degrees and [SPY1] should show the end ring of the telescope framing the top of the open dome. The azimuth positions for each telescope should be: S1, S2 82.0 - E1, E2 55.9 - W1, W2 99.3\\ | ||
+ | On the Power GUI, turn on the [Tel AZ] and [Tel EL] power for each of the active scopes (green means ON).\\ | ||
+ | The new for 2016 stall detection function usually has each scope disabled each evening. They will need to be enabled before checking the dome servers or slewing. Make sure that the telescopes do not move away from their stow positions when enabling the scopes. If they begin moving, then click [STOW] on the Telescope Control Tab or dome gui and make sure that they arrive at the correct stow position. Check for problems with the dome servers by watching each telescope move to the precise stow position, ie. 89.990º and moving to 90.000º. If it stays off the precise stow position, the dome sever may need restarting. Click [REOPEN] on the dome gui if the clock is not the same as the CHARA time. | ||

+ | \\ | ||
+ | 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, 6.4 Manually Stowing the Telescopes | ||
- | \\ | + | 6.2 Start the end night sequence on Cosmic Debris |
- | === 6.1 End Night Sequence | + | Clear the job queue on Cosmic Debris. Press the [END NIGHT] button on Cosmic Debris. This will close all the shutters, stow the active telescopes, close the telescope mirror covers, send the active OPLE carts to the back switch, close the OPLE socket, and archive the accumulated data for the night. NOTE: The End Night Sequence will NOT close the dome slits so these will have to be closed manually after all of the telescope M1 mirror covers are closed. It will also not send inactive carts back. Update the configuration with any inactive scopes to make sure those carts can be sent back manually as well. The Cosmic Debris status window will indicate when the end night sequence is complete. You can close Cosmic Debris after you have sent out the Observing Report. * If you use the End Night sequence to stow the telescopes and close mirror covers, remember to do a visual check of all telescopes using the check list in step 6.4 below before turning off the power for the telescopes and closing the telescope GUIs.\\ |
+ | A list of observed targets and an Observing Report is now automatically generated as part of the End Night Sequence. Click [END NIGHT], then [REPORT] on Cosmic Debris to generate this automatic report email. The report will include the headings: PI name, Program, Observers, Baselines, Weather and Seeing data, and targets on which data was collected. Complete the Observers and Baselines entries, add comments to the bottom of the report and put your name at the end. Check with the observer for completeness of the target list. Some observers will send you comments of their own. Add those to the report. Cut and paste this into an email to CHARA Obs and send it. When the function works, you can also hit the SEND button at the bottom of the report to email this report to the CHARA OBS list.\\ | ||
+ | Note: Classic, CLIMB, FLUOR and PAVO will automatically send the target information to Cosmic Debris after data is acquired. For MIRCx, the [DATA ACQUIRED] button can be clicked on Cosmic Debris after each data sequence is finished or it can be done by the MIRCx operator from his or her station.\\ | ||

+ | If you have other technical information to send out that is not related to the nightly observing runs, use our other lists that pertain to the subject at hand.\\ | ||
+ | \\ | ||
+ | In addition to paper observing logs, CHARA offers the option of using electronic logs. At minimum, we request that you fill out the date, UT time, target name, and any comments that would be relevant for subsequent reduction.
