APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday September 3, 2007 (MJD 54347) ---=== OBSERVING TEAM ===--- Viktor Malanushenko, Shannon Watters Steph Snedden (support), Kaike Pan (support), Fritz Stauffer (phone), Eric Neilsen (phone), Connie Rockosi (phone), Rick Kessler (phone), Kurt Biery (phone) ---=== OBSERVING PLAN ===--- ACCURATE SNe Science ---=== OBSERVING SUMMARY ===--- While lowering the instrument lift after mounting the imager it stopped and wouldn't move down anymore until it was moved back up to the bottom of the imager. We also had the 'old' problem with g1 on the initial bias (see log). We spent the majority of the night starting and ending imaging runs while troubleshooting the astrom/skippy problem. The problem wasn't solved but Eric Neilsen and Kurt Biery think they have narrowed it down to a time issue with the DA. They will work on it more during the day. We did manage to get a some science without skippy but did have some watcher errors (see log and problems). Run 6924 from lambda=113 to 123 including ramps and run 6930 from lambda=162 to -123 including ramps. If you look at the Imaging Run Summary you'll see that the start and end lambdas for each science run are identical but the idReport looks normal as far as we can tell. ---=== OBSERVING LOG ===--- Afternoon: --------- While running an afternoon checkout imager bias (tbars latched, in the dog house), the "old" problem with g1 (it's purple) cropped up. We expect it to correct itself when we take an on-telescope bias with the tbars unlatched. Night: ----- 01:31Z Run 6923. On-telescope imager bias. Chip g1 looks good (see afternoon). 02:18Z Run 6924. SN Stripe 82 S Focus happy at frame 39. Seeing ~2.0". Skippy is unhappy, LtMatch confirms that the rotator pointing is good. 02:20Z goDrift: lambda=106 02:48Z Ramp start: lambda=113, frame 49 02:56Z Science start: lambda=115, frame 63 03:19Z Science end: lambda=121, frame 103 03:27Z Ramp end: lambda=123, frame 119 Reverting to iop v4_35_0 to see if it will please skippy. 03:38Z Run 6925. SN Stripe 82 S. Focus happy from the start. Seeing ~1.8". Skippy is unhappy, LtMatch confirms that the rotator pointing is good. 03:38Z goDrift: lambda=121.0 03:40Z Ramp start: lambda=121.5, frame 9 03:48Z Science start: lambda=123.5, frame 23 Looking at the RA in the gang files (RA=lambda+185) we found an offset in this run. The RA converts to a lambda which is 5.4 degrees larger than it is in tccMon (we checked 6924 & 6921 and didn't find the same offset). The lambda reported here is from tccMon. 04:17Z Science end: lambda=130.25, frame 67 04:25Z Ramp end: lambda=132.25, frame 80 Reverting back to the current iop v4_38_0. 05:08Z Run 6926. SN Stripe 82 S. Focus happy from the start. 05:09Z goDrift: lambda=146.5 Looking at the gang files we find both the RA and AZ are 60.000000 in all the frames and both the Dec and Alt are 75.000000. The run was declared BAD. 05:25Z Run 6927. SN Stripe 82 S. Same problem as the previous run. Run declared BAD. Hard reboot of the MCP. Fritz sent us this output from the reboot: TimerStart 20, 5, serverDCStart value = 1 = 0x1 ipsdss_ini value = 0 = 0x0 set_rot_state -1 value = -1 = 0xffffffff ffs_enable 1 /* enable the Flat Field Screen */ value = 0 = 0x0 dbgInit value = 0 = 0x0 06:12Z Run 6930. SN Stripe 82 S. Focus good at frame 14. Seeing~1.7". Skippy still isn't happy. LtMatch confirms that the rotator pointing is good. 06:15Z goDrift: lambda=160.4 06:21Z Ramp start: lambda=162, frame 18 06:29Z Science start: lambda=164, frame 31 tccMon and mcpMenu agree on the RA and Dec but they don't agree with the file headers. Eric asked us to check what time iop was getting from the DA. It turns out the value corresponded to the beginning of the run and did not increment with time: im> iccExec ad1 statusGet tccRA {ad1 345.20585194309} im> iccExec ad1 statusGet tccRA {ad1 345.20585194309} im> iccExec ad2 statusGet tccRA {ad2 345.20585194309} im> iccExec ad3 statusGet tccRA {ad3 345.20585194309} im> iccExec ad4 statusGet tccRA {ad4 345.20585194309} Eric decided we should get Kurt Biery involved. We had watcher errors during frame 228 (see problems) We had another watcher error for frame 499 (see problems) 11:12Z Science ended: lambda=-125, frame 506 11:20Z Ramp ended: lambda=-123, frame 520
