-* Before entering the lab, you must have a reason or tasks at hand. * 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 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.\\+* Before entering the lab, you must have a reason or tasks at hand.

[COMMS] has been replaced by Tiptilt Socket as well. === 3.3 Open servers required for observing === * Open servers from the pop up menu at bottom of screen 5, using the black platter icon. * The GPS server should always stay on and remain on screen 3 * The METROL Server also stays on in screen 3 * Close and re-open all Telescope servers after UT 0h in screen 3 (because of tiptilt connection issues) * Open Primary OPLE Server (Move to upper left of screen 6) * Open Classic, Climb1, or Climb2 if needed (Move to middle left of screen 6) * Open Tiptilt Server (Move to lower left of screen 6) * Open Metrology Monitor (METROL) gui, (upper right of screen 3), this gui usually remains open. * Open Metrology Laser (METLAS) gui, (upper right of screen 3), this gui usually remains open. === 3.4 Open Telescope GUIs from the menu === * Open needed Telescope guis, put on screen 5. All 6 scope guis can fit on one screen, but the TV windows will overlap slightly if all 6 are used for MIRC observing. * On the main tab for each telescope gui, click [ON] under Television to turn on the TV screen === 3.5 Open GUIs required for observing from the menu under GTK: === * Open Primary OPLE gui (move to right side of OPLE server) * Open Classic, Climb1, or Climb2 gui if needed (put on right side of server) * Open LDC1 and LDC2 if VEGA or PAVO programs are observing * Open Tiptilt GUI * This will bring up Tiptilt GUI and Tiptilt viewing screens for all telescopes * Move viewing screens near telescope TV screens === 3.6 Using the Cosmic Debris job sequencer ===\\
 Open Cosmic Debris, CD for short, - Primary from the menu and move to screen 4 * On the CONFIGURE tab, check to make sure the PoPs and telescope beam assignments agree with the white board * If the POPs are wrong on CD, then open the "PoPs" GUI from the menu * Click on the [Overview] button on the PoPs GUI * If nonsense comes up in the overview, then click [FLUSH] and then [REOPEN] on the PoPs GUI * Then click [UPDATE] on the PoPs Overview * If the PoPs Overview is now correct, then click the [GET] button on the CD Control Tab, this should update the PoPs * If the beams are not assigned correctly, move the beams accordingly to the proper telescope using the BeamSampler GUI and click [GET] on CD to update * Select the active telescopes on the tab labeled "Configure" * Choose a suitable reference cart, using the same one from the night before to make fringe finding easier. * After everything is set correctly, then click [SEND] on Cosmic Debris to send the active scope information to Ople\\ Open Cosmic Debris, CD for short, - Primary from the menu and move to screen 4 * On the CONFIGURE tab, check to make sure the PoPs and telescope beam assignments agree with the white board * If the POPs are wrong on CD, then open the "PoPs" GUI from the menu * Click on the [Overview] button on the PoPs GUI * If nonsense comes up in the overview, then click [FLUSH] and then [REOPEN] on the PoPs GUI * Then click [UPDATE] on the PoPs Overview * If the PoPs Overview is now correct, then click the [GET] button on the CD Control Tab, this should update the PoPs * If the beams are not assigned correctly, move the beams accordingly to the proper telescope using the BeamSampler GUI and click [GET] on CD to update * Select the active telescopes on the tab labeled "Configure" * Choose a suitable reference cart, using the same one from the night before to make fringe finding easier. * After everything is set correctly, then click [SEND] on Cosmic Debris to send the active scope information to Ople\\
