APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday November 20, 2008 (MJD 54791) ---=== OBSERVING TEAM ===--- Kaike Pan and Howard Brewington (observers) Steph Snedden (swing) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Most of the night was lost to high humidity; however, we completed all of the cloudy-night tasks, i.e., spectro and imager monthly checkouts as well as sparse-plugged plate tests. Added signal to plate 3160 ---=== OBSERVING LOG ===--- Afternoon: --------- Spectrograph focus adjusted for somewhat colder temps, without going out of spec for early night plates. Details are in the problems section. A fog bank to the east caused a rise in humidity. Building was kept closed and ventilation was delayed. Night: ----- 23:57Z Sunset 01:10Z Humidity was at ~97%; we mounted the imager for cloudy night tasks. 01:25Z Evening twilight ended. 01:36Z Run # 7826 On-telescope bias; see Problems Section for checkBias results. The biasGen and biasCheck results are also posted in the Problems Section. Images looked good. 02:05Z Run # 7827 On-telescope flat; see Problems Section for results. Images looked good. All of the fits_files from above tests were moved to Phoenix:/data/photo/optics/54791 03:00Z Dismounted imager and remounted cart 03 for spectro monthly checks. Bias loop was done; images looked fine; see apo_plotbias below: Filename 02% 05% 10% 50% 90% 95% 98% ------------------- ------ ------ ------ ------ ------ ------ ------ sdR-b1-00056522.fit -5.7 -3.7 -2.6 2.0 7.5 8.9 10.8 sdR-b2-00056522.fit -7.9 -5.8 -4.6 1.7 6.8 9.3 10.5 sdR-r1-00056522.fit -7.0 -5.1 -3.7 1.7 7.2 8.9 10.5 sdR-r2-00056522.fit -7.9 -6.0 -3.9 1.3 6.8 8.7 10.8 Done for 95.462021 sec. % Program caused arithmetic error: Floating underflow % Program caused arithmetic error: Floating illegal operand IDL 5.5a> apo_plotbias, 56522 04:11Z Dithered flats were done next; images looked good. 04:15 56547 10.0 flat 04:19 56548 10.0 flat 04:23 56549 10.0 flat 04:27 56550 10.0 flat 04:31 56551 10.0 flat 04:36 56552 10.0 flat 04:40 56553 10.0 flat 04:44 56554 10.0 flat 04:48 56555 10.0 flat 04:52 56556 10.0 flat 04:56 56557 10.0 flat 05:00 56558 10.0 flat 05:04 56559 10.0 flat 05:08 56560 10.0 flat 05:13 56561 10.0 flat 05:17 56562 2.0 arc 05:19 56563 2.0 arc 05:55Z Spectro darks; images looked good; see apo_plotbais below: Filename 02% 05% 10% 50% 90% 95% 98% ------------------- ------ ------ ------ ------ ------ ------ ------ sdR-b1-00056565.fit -2.9 -0.7 0.4 5.9 12.1 14.2 16.3 sdR-b2-00056565.fit -4.8 -2.4 -1.1 5.2 12.4 14.0 17.4 sdR-r1-00056565.fit -4.7 -2.9 -1.7 4.3 10.3 12.3 14.5 sdR-r2-00056565.fit -5.2 -3.7 -2.0 4.3 9.9 12.0 14.8 Done for 73.785687 sec. % Program caused arithmetic error: Floating underflow % Program caused arithmetic error: Floating illegal operand IDL 5.5a> apo_plotbias, 56565 06:45Z IRSC became covered with ice; we used a heat gun and kim-wipes to clean it.
