Date: Thu, 9 Sep 2004 09:27:41 GMT From: snedden@apo.nmsu.edu (Stephanie Snedden) Subject: 2.5m obslog 20040908 (MJD 53257) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday September 8, 2004 (MJD 53257) ---=== OBSERVING TEAM ===--- Steph Snedden collimators: French Leger Larry Carey Russell Owen ---=== OBSERVING PLAN ===--- Pre-shake items - fiducial tables, spectro monthly checkout ---=== OBSERVING SUMMARY ===--- Planned items finished ---=== OBSERVING LOG ===--- Pre-shakedown. 1) French, Larry & Russell collimated M2 this afternoon & I lent moral support and took notes. We are ready for the final check of collimation. 2) New fiducial tables were generated. Alt fiducial 6 was not read, so I opted not to check the alt table in. The alt table that is current is dated August 6, and the values for fiducial 1-5 crossings were similar to today's table, so it should be good. The new rot and az tables were checked in and declared current. The new az table includes fiducial 20, which was missing from the August 6 data. The new mcp_fiducials version is v1_22. 3) The primary was homed and relaxed, using Russell's NEWRELAX script. It now runs for 4 cycles. The secondary was homed. New nominal mirror numbers were set. 4) A bias drift with the t-bars unlatched ran for approx. 700 frames. During the afternoon, Jon saw low frequency noise in the bias in dewar 3 (yes, 3, not 1). Since it's probably best to look for noise in all the dewars as a result of this, I copied frames from ALL the dewars to phoenix in /data/photo/bias53257. Given limited disk space on sdsshost, and limited time, I was only able to copy over about 10% of all the data. Even so, it's a LOT of data for someone to look through! Since Jon saw the noise pretty early on, it is hopefully in the frames I copied. I did not see any noise at any time, myself, but I only watched the monitors sporadically. T-bars were latched at the end of the drift. 5) Spectro Monthly Checkout: --------------------------- Original mirror values: sp1: Coll_motor_A -27 Coll_motor_B 947 Coll_motor_C -1328 sp2: Coll_motor_A 348 Coll_motor_B -1853 Coll_motor_C -3550 A slight adjust was made to the X-position of sp2 (4 pix to the right). New values: sp2: Coll_motor_A -48 Coll_motor_B -2253 Coll_motor_C -3151 Wavelength adjust was made to sp2 (lower, or bluer, by 5 pix). Forgot to record the new values before I moved on to the collimation. The collimate procedure asked for the following: sp1, red: COLLIMATE: Min offset = -0.09 pix COLLIMATE: Max offset = 1.16 pix COLLIMATE: RMS across CCD = 0.35 pix COLLIMATE: Mean offset = 0.44 pix COLLIMATE: Camera r1 appears to be OUT-OF-FOCUS (|mean| > 0.15 pix) COLLIMATE: Predict (red) piston movement of -4036 steps for spectro-1 COLLIMATE: Issue SOP command: "sp1; mechPiston -4036" sp2, red: COLLIMATE: Min offset = -0.40 pix COLLIMATE: Max offset = 0.55 pix COLLIMATE: RMS across CCD = 0.24 pix COLLIMATE: Mean offset = 0.12 pix COLLIMATE: Camera r2 appears to be IN-FOCUS (|mean| collimate,28394 Reading /data/spectro/53257/sdR-b1-00028394.fit Reading /data/spectro/53257/sdR-b1-00028395.fit COLLIMATE: Min offset = -0.50 pix COLLIMATE: Max offset = 0.76 pix COLLIMATE: RMS across CCD = 0.33 pix COLLIMATE: Mean offset = 0.15 pix COLLIMATE: Camera b1 appears to be OUT-OF-FOCUS (|mean| > 0.15 pix) COLLIMATE: Predict blue camera ring movement of -5.5 degrees for spectro-1 COLLIMATE: (if red is already in focus) Log file = Collimate-53257-b1-00028394.log PostScript file = Collimate-53257-b1-00028394.ps Reading /data/spectro/53257/sdR-b2-00028394.fit Reading /data/spectro/53257/sdR-b2-00028395.fit COLLIMATE: Min offset = -0.63 pix COLLIMATE: Max offset = 0.18 pix COLLIMATE: RMS across CCD = 0.22 pix COLLIMATE: Mean offset = -0.20 pix COLLIMATE: Camera b2 appears to be OUT-OF-FOCUS (|mean| > 0.15 pix) COLLIMATE: Predict blue camera ring movement of 7.1 degrees for spectro-2 COLLIMATE: (if red is already in focus) Log file = Collimate-53257-b2-00028394.log PostScript file = Collimate-53257-b2-00028394.ps Reading /data/spectro/53257/sdR-r1-00028394.fit Reading /data/spectro/53257/sdR-r1-00028395.fit COLLIMATE: Min offset = -0.29 pix COLLIMATE: Max offset = 0.80 pix COLLIMATE: RMS across CCD = 0.30 pix COLLIMATE: Mean offset = 0.12 pix COLLIMATE: Camera r1 appears to be IN-FOCUS (|mean| < 0.15 pix) COLLIMATE: Predict (red) piston movement of -1097 steps for spectro-1 COLLIMATE: Issue SOP command: "sp1; mechPiston -1097" Log file = Collimate-53257-r1-00028394.log PostScript file = Collimate-53257-r1-00028394.ps Reading /data/spectro/53257/sdR-r2-00028394.fit Reading /data/spectro/53257/sdR-r2-00028395.fit COLLIMATE: Min offset = -0.37 pix COLLIMATE: Max offset = 0.46 pix COLLIMATE: RMS across CCD = 0.20 pix COLLIMATE: Mean offset = 0.11 pix COLLIMATE: Camera r2 appears to be IN-FOCUS (|mean| < 0.15 pix) COLLIMATE: Predict (red) piston movement of -1038 steps for spectro-2 COLLIMATE: Issue SOP command: "sp2; mechPiston -1038" Log file = Collimate-53257-r2-00028394.log PostScript file = Collimate-53257-r2-00028394.ps Dithered flats were taken - frames 28396 - 28402 (flats), frames 28403, 28404 (arcs).
