APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday March 29, 2010 (MJD 55285) ---=== OBSERVING TEAM ===--- Dmitry Bizyaev Steph Snedden Support: Jon Brinkmann ---=== OBSERVING PLAN ===--- Pointing model, then MARVELS ---=== OBSERVING SUMMARY ===--- 72 point pointing model implemented. SKY RMS = 1.87 Popn SD = 2.06 MARVELS plates observed: Cartridge 8, plate 3413B XO-1 No spectra in fibers 3, 4 (green #1 - black, cyan); 43, 44 (green #2 - black, magenta) Cartridge 9, plate 3796A - FIELD1348 Cartridge 7, plate 3903A - K4 Cartridge 7, plate 3903B - K7 ---=== OBSERVING LOG ===--- Afternoon: --------- Craig asked for light down fibers to the spectrographs. Unfortunately, all BOSS cartridges were removed from the bay to the back wall rack, so were unavailable. We wound up removing the cover from a MARVELS cartridge and turning on the enclosure lights plus left the door open so Craig could get scattered light down some fibers to look at. I believe this was for the dithered flats. 180-liter dewar was low when we came in. Night: ----- We mounted the engineering camera for a pointing model. Rather than use SOP and fsaoimage, we used the script "mondir2ds9" to display the engcam images. This script is in observer's bin directory on sdsshost2. Thanks to Jon for overseeing the data fiber connection and guider Mac health. When we started host sessions for M1 and M2 to home and relax, we got this message "data set hang-up" and were bumped back to the TCC. The second attempt to connect to the controllers worked. The center of the eng cam CCD appears to have moved. We updated I_CA1_ENGCAM.DAT;40 with the new center values; 776, 533.
