APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday December 31, 2003 (MJD 53005) ---=== OBSERVING TEAM ===--- Swing: Howard Brewington Night: Dan Long Pete Newman ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Clouds and later snow kept us closed all night. The spectrographs are now completely back in spec. A couple inches of snow prompted late night snow removal. ---=== OBSERVING LOG ===--- Afternoon Checkout: ------------------- Spectro focus was checked. And in IDL/collimate, both spectrographs were displayed as in-focus. Night: ------------------- Early this evening we noticed that the mcp was saying sp2's door was closed. It clearly wasn't because there was a cartridge mounted. A check of the instrument change control panel showed neither open nor closed leds lit for sp2. Cycling the doors from the panel (with the cartridge removed), got the door state to display correctly. The NGOODFIBERS mystery is solved. Apparently SoS had found a local minimum in the X-direction one fiber bundle to the right, giving the indication that the X-positional parameters were OK. A look at a flat this afternoon showed a bundle "missing" from the right side of the chips. -12000 -12000 12000 collimator steps later, the missing bundle shifted back in from the left, and NGOODFIBERS was back within a few of 320. Now if we could only solve this cloud problem.... Snow started falling lightly after midnight. Heavier snow started after 10Z. Below are the collimator moves issued to correct the X-position and tweak the other parameters. Initial sp2 positions: Coll_motor_A -20731 Coll_motor_B 18299 Coll_motor_C -10300 Need to move to increasing X by 20 fibers = ~120 pixels at 100 steps/pixel: mechMoveColl -12000 -12000 +12000 postCal shows we still need to move another 11.2 pixels (mean of the Xmin/Xmax errors from b2/r2), so: mechMoveCol -1120 -1120 +1120 Now fix the wavelength range, to move it by -15 Angstrom at blue end = -15 pixels, by -19 A at red end = -8.6 pixels, so move mean = -11.8 pixels: mechMoveCol -1180 +1180 0 Final sp2 positions: Coll_motor_A -35031 Coll_motor_B 6357 Coll_motor_C 2820 At this point, all of Xmin, Xmax, Xsigma, Wavemin, Wavemax, Wsigma are in the black for SoS, Tambient = +4.4C in the enclosure. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 4356 22:04Z 22:19Z 100 O 140.14 143.93 39 ignore ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- ---=== LTMATCH RESULTS ===--- Run Field nFields alt az nGood rowMean rowSig colMean colSig rot ------------------------------------------------------------------------ ---=== SPECTROSCOPY DATA SUMMARY ===--- Summary Checked (y/n):y QA Procedures Done (y/n):y b1-L: 1220 hot col 154 b1-R: 1038 b2-L: 1242 b2-R: 1211 r1-L: 1190 r1-R: 1239 hot col 1154 rightmost fiber cut off at upper right. r2-L: 565 r2-R: 1429 hot col 1475 rightmost two fibers cut off at upper right.
