APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday April 9, 2010 (MJD 55296) ---=== OBSERVING TEAM ===--- Kaike Pan Steph Snedden r2'ers: Connie Rockosi (UCO-Lick) Jim Gunn (PU) Michael Carr (PU) Visitors: Muwen Pan Stephen Pan Sophie Pan ---=== OBSERVING PLAN ===--- BOSS Science without r2 ---=== OBSERVING SUMMARY ===--- The following BOSS plates were observed: Cartridge 10, plate 3826 - DONE without r2 Cartridge 11, plate 3834 - DONE without r2 Cartridge 12, plate 3970 - DONE without r2 Cartridge 13, plate 3987 - DONE without r2 Cartridge 17, plate 3946 - DONE without r2 Cartridge 16, plate 3851 lots of S/N, but we will keep it plugged since we have no other plates for that time slot. We measured the focus offset for guide fiber 9 on cartridge 10. It was clearly out of focus in guider images. Details are in the log. French plans to make the physical measurements of that fiber today. Visually, it appeared to be at the same height as the other short fibers. We noted other out of focus guide fibers in the log, but did not measure the focus offsets. French, we occasionally heard a clicking sound during rotator motion that sounded like it came from the wrap. ---=== OBSERVING LOG ===--- Afternoon: ---------- Afternoon checkout was mainly without problems.We did hear a periodic clicking noise when the rotator moved that sounded like it came from the rotator wrap. Note that cart. 16 has a different focus setting and *MID settings than cartridge 10. Cartridge 10 was in spec, cartridge 16 was not. Night: ------ We used the test web interface to the plate db on port 8083. I like the color coding on the (S/N)^2, Demitri. Nice. It was spitting out zeroes for r2's (S/N)^2 without crashing. Cartridge 10, plate 3826 - BOSS ------------------------------- GSOGTF Guide fiber 9 had a significantly different focus than 1, 8 or 16 (the short group). We ran Paul's guider focus sweep test. 9's best focus was different by 200 fom the other fibers. Best focus on all fibers was frame 51, focus 646 Guider off Focus offset: -150 frames 58 - 61 -100 frames 63 - 65 -50 frames 66 - 68 0 frames 70 - 72 50 frames 74 - 76 100 frames 79 - 81 150 frames 83 - 85 200 frames 88 - 90 When dismounting the cartridge we inspected fiber 9. It appeared to be at the same level as fiber 8, so we suspect the offset could be at the terminal end.
