Subject: 2.5m obslog 20160822 (SJD 57623) From: kpan@apo.nmsu.edu Date: Tue, 23 Aug 2016 11:42:03 +0000 (UTC) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday August 22, 2016 (SJD 57623) ---- Observing Team ---- Elena Malanushenko Kaike Pan Connie Rockosi (online) John Downey Jon Brinkmann Dan Long (phone) ---- Observing Summary ---- The night started with cloudy sky relatively high humidity, and developed to high humidity (at 90%). We spent several hours attempting to debug issue on SP1: all pixels have zeros values on on all frames of bias, dark, flat, and arc. Manually focused B2 and R2, took focus sweep data with cart 5. Manually focus SP2 with sparse plugging plate on cart 4. Took hartmann with warmed-up lamps and one flat and 4 arc with warmed-up lamps. Problems: 1) I heard a weak air leakage on SP2, but cannot locate the exact spot of the leakage. 2) All frames (bais, dark, flat, and arc) have values of zeros on all pixels. Contacted with Connie, John, Jon, Dan, and the problem is still not resolved. 3) sp1 has a problem with autofill. "startfillseq" had to be issued. 4) The entire Manipulator control box didn't have power, power switch inside the plugged building was checked, and confirmed fine. JohnD was called (thanks to JohnD and sorry to wake you up). He found that the UPS for the manipulator was overloaded. Resetting fixed the problem. Elena checked the manipulator and found no problem during afternoon checkout. Why the UPS get overloaded reminds unknown. Note to developers and engineers: 1. According to Renbin, B2 and R2 have tilts in opposite sign. Originally, B2 has a shim, and R2 didn't. If removing the shim on B2 fixes B2 tilt, will installing shim fix the tilt on R2? 2. Jon B. compared fits files of b1/r1 with that of b2/r2, and found differences in key words. We thought these may offer clues to solve the SP1 problem, so post here: sdR-b1-00225445.fit:ERRCNT = '2114' sdR-r1-00225445.fit:ERRCNT = '2114' sdR-b2-00225445.fit:ERRCNT = 'NONE' sdR-r2-00225445.fit:ERRCNT = 'NONE' sdR-b1-00225445.fit:SYNCERR = 'NONE' sdR-r1-00225445.fit:SYNCERR = 'NONE' sdR-b2-00225445.fit:SYNCERR = 'NONE' sdR-r2-00225445.fit:SYNCERR = 'NONE' sdR-b1-00225445.fit:PIXERR = '2112' sdR-r1-00225445.fit:PIXERR = '2112' sdR-b2-00225445.fit:PIXERR = 'NONE' sdR-r2-00225445.fit:PIXERR = 'NONE' sdR-b1-00225445.fit:PFERR = '1' sdR-r1-00225445.fit:PFERR = '1' sdR-b2-00225445.fit:PFERR = 'NONE' sdR-r2-00225445.fit:PFERR = 'NONE' ---- Observing Plan ---- Shakedown spectrograph tests ---- Observing Log ---- Afternoon ----------- Tested actors.All ok. 00:07:51 apogee evening calibrations. eBoss bias and dark were ok.

I have visually checked hartmann and bias. All sp1 spectra do not have light. 1:30 Moved apogee gang to 1m port and started its actor. Telescope has been checked, all was ok. Fiducials has been set. 02:50 started ventilation. 03:20 stopped ventilation because of high humidity. Night ------ We also had problem with sp1 and continue consultations with Connie, Dan Long, John. It is still not clear what to do with it. The humidity was rized and we stopped ventilation and kept closed. We did "sop collimateBoss" and found out that b2 was too much out of focus. We tried b-ring turns in one direction and in the other, selected when to turn, and turned -650 degrees before we found good focus. We looked and compared all images visually. After that, we did hartmann refinement. 6:20 we got critical alert on sp1, we found out that sp1 autofill was not triggered fill. We applied startFillSeq and filled dewars. To run requested test for b2, we needed to mount cart 5 (we have had cart 11). We could not move manipulator arm, and we did not notice any power in manipulator power box. Called to John Downey for help. 08:00Z: Focus sweep test after the shim on B2 removed. 3 biases: 225484-487. hartmann indicated SP2 are in focus: 225492-493. Since R1/B1 don't work, only SP2 collimator was moved during the process. Three pairs of hartmann with warmed-up lamps: 225494-499. sop doBossCalibs nflat=1 narc=1: 225500-501 ==== boss moveColl spec=sp2 a=10000 b=10000 c=10000 sop hartmann mcp ff.on boss exposure flat itime=25 mcp ff.off mcp hgcd.on mcp ne.on boss exposure arc itime=4 mcp hgcd.off mcp ne.off ======== Frames 225502-505 == ==Loop the command set twice, frames 225506-513 == boss moveColl spec=sp2 a=-2500 b=-2500 c=-2500 sop hartmann mcp ff.on boss exposure flat itime=25 mcp ff.off mcp hgcd.on mcp ne.on boss exposure arc itime=4 mcp hgcd.off mcp ne.off ==== == Take 2 sets of hartmann with fully warmed lamps, frames: 225514-517 == mcp hgcd.on mcp ne.on tui wait 240 sop hartmann mcp hgcd.on mcp ne.on tui wait 240 sop hartmann ============ ==Loop the command set 4 times, frames 225518-533 == boss moveColl spec=sp2 a=-2500 b=-2500 c=-2500 sop hartmann mcp ff.on boss exposure flat itime=25 mcp ff.off mcp hgcd.on mcp ne.on boss exposure arc itime=4 mcp hgcd.off mcp ne.off ==== == Take 2 sets of hartmann with fully warmed lamps, frames: 225534-537 == mcp hgcd.on mcp ne.on tui wait 240 sop hartmann mcp hgcd.on mcp ne.on tui wait 240 sop hartmann ============ ==Loop the command set 2 times, frames 225538-545 == boss moveColl spec=sp2 a=-2500 b=-2500 c=-2500 sop hartmann mcp ff.on boss exposure flat itime=25 mcp ff.off mcp hgcd.on mcp ne.on boss exposure arc itime=4 mcp hgcd.off mcp ne.off ==== == Move collimator back to the starting position, and take a set of data, frames 225546-549 ==boss moveColl spec=sp2 a=10000 b=10000 c=10000 sop hartmann mcp ff.on boss exposure flat itime=25 mcp ff.off mcp hgcd.on mcp ne.on boss exposure arc itime=4 mcp hgcd.off mcp ne.off ======= ==Take two sets of hartmann with fully warmed lamps, frames 225550-553 == mcp hgcd.on mcp ne.on tui wait 240 sop hartmann mcp hgcd.on mcp ne.on tui wait 240 sop hartmann Mount cart 4, plate 9050, focus SP2.
