APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday September 23, 2010 (MJD 55463) ---=== OBSERVING TEAM ===--- Audrey Simmons Steph Snedden Paul Harding (Case) Craig Loomis (via STUI and phone - PU) ---=== OBSERVING PLAN ===--- Engineering and MARVELS ---=== OBSERVING SUMMARY ===--- We spent most of the night working on the new engcam instrument block and FK5inFiber. There was not enough time to do a pointing model at the end of the night, so we gave the remaining time to MARVELS. Pointing model will be tomorrow night. Marvels fields done: Plate 3633A - GJ176 Plate 3633B - FIELS1631 Plate 3896A - HD37605 We kept getting "max acceleration exceeded" messages for altitude during slews. It could be it was moth lubrication on the drive surface, or it could be that the limits need looking at. Several times we saw the rotator in a "Halting CannotCompute" state when slewing to a star, then after a pause the rotator would start back up and finish its move with no intervention from us. A heads-up that the ThAr counts are very low - 29 on the PMT Dan, I think it would be okay to raise the pressure on the MARVELS clean air nozzle by another 5 to 10 psi. ---=== OBSERVING LOG ===--- Afternoon: --------- ecamera actor was down, all others were fine. Paul restarted the ecam actor.

First up: finish the new engineering camera instrument block. Note: You need to first load an instrument block with a gprobe in order to have track/pterr work on the engcam. Since we are trying to create the new engcam inst block, we just loaded a wrong one from last months engcam work. Best focus: -450 02:38Z - Ran Elena's grid and ring scripts, and edited the new instrument block. Note: The instrument block instructions for the 3.5m indicate that you can use any value for rot_inst_ang in Russell's program when analyzing the grid. Our experience was that you have to enter the value from your current instrument block into the program. The instrument block "engcam_0deg" is now correct and should be loaded for engineering camera on-axis work. 05:00Z - Mounted cartridge 10 for Craig and Paul's FK5inFiber work. They needed to determine the offset directions for the large fibers in terms of boresight offsets. They were able to acquire an FK5 in fiber 11 on cart 10, then worked on getting the fiber center in the spectro instrument block. It should not be too long before we have FK5inFiber. 08:10Z - Switched to MARVELS since there was not enough time left to implement the new fiducial tables plus get a full-blown pointing model.
