Subject: 2.5m obslog 20160820 (SJD 57621) From: kpan@apo.nmsu.edu Date: Sun, 21 Aug 2016 09:55:07 +0000 (UTC) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday August 20, 2016 (SJD 57621) ---- Observing Team ---- Kaike Pan ---- Observing Summary ---- The first half was cloudy. Humidity was high in the 2nd half. AGOEE 1m: the Gang connector was move to 1m port and 1m actor was started at UT 2:40. Shakedown tasks: Camera rotation angles were measured with flat images. The rotation angles are 0.04, 0.4, 0.004, and 0.001 degrees for B1, R1, B2, and R2. They all are within 0.5 degrees. Lossy fiber test data on SP2 was collected. Data frames are 225322 - 225363 for R2, and 225364 - 225373 for B2. See log for more details. linearity test data was collected. The corresponding flat frames are 225379 to 22538 (exposure time from 15 seconds to 0 seconds). See log for more details. Note for eBOSS and MaNGA teams: =============================== With spared B2 and R2, data for 1) biases and darks; 2) Focus Sweep test; 3)Focus drifting test; 4)Sparse plugging test for Xmid; 5)Sparse plugging test for Wmid; 6) Lossy fiber test on SP2; 7)Linearity test; 8) Rotation angles on cameras were measured. Those data should be able to characterize B2 and R2. eBOSS and MaNGA need to make decision whether the spared B2 and R2 should stay on or the original ones should be swapped back on. The swap may take couple of days. ---- Observing Plan ---- Shakedown tasks ---- Observing Log ---- Afteroon: ========= APOGEE evening calibrations was taken and checke. the Gang connector was move to 1m port and 1m actor was started at UT 2:40. Night: ===== Rotation angles of cameras were measured with fiber images of flats. The rotation angles are 0.04, 0.4. 0.04, and 0.01 degrees for B1, R1, B2, and R2. Lossy fiber test on SP2: ======================== Because cartridge 8 is not plugged with any plate, it cannot be loaded into SOP. The fit headers of exposure have cartridgeID = 11 instead of 8. test exposure 225320, 150 sec. max DN at 39K test exposure 225321, 200 sec. max DN at 54K 180 sec was decided to use as the exposure time for the test. with the exposure time of 180 sec, The max DN is at 48K.
