APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday November 2, 2008 (MJD 54773) ---=== OBSERVING TEAM ===--- Elena Malanushenko (swing) Audrey Simmons Dmitry Bizyaev ---=== OBSERVING PLAN ===--- Science! Nov 2008 54773.0 0.32 BOSS/SEGUE 10.4 hours ---=== OBSERVING SUMMARY ===--- We added signal to plates 3128, 3146, and 3116 (SEGUE), and 2962 (BAOtest). We finished plate 3114 (cart 7), SEGUE, and 3041, cart 9) Marvels pre-selection. Plate 3040 (cart 3), Marvels preselection, has been collected necessary number of exposures and has been done, according to the newest Marvels criterium. Plate 3116 has no correct magnitudes in plugMapM file, so SoS cannot reduce it. See "problems" section for description and some workaround. ---=== OBSERVING LOG ===--- Afternoon: ========== All systems are checked and they work properly.

Similar problem happened with plate 3114 a few days ago. All plug files are in their place. We see signal in fibers. The problem is with magnitudes for the target stars in the file plPlugMapM: most of them equal to 25. This confuses SoS. I checked if there are other plug-files on sdsshost2 or plate-mapper. No, the original file was made with plPlugMapP on plate-mapper, and those magnitudes are all 25 in plPlugMapP. We didn't find a quick fix and complete only 3 exposures with this plate. The same problem with 3114 was fixed manually. The old plugP files (plPlugP...ori) and new plugP files on plate-mapper can be found. I wrote a script that check if we should expect more problems like this, i.e. are there any SEGUE plugP files on plate-mapper in all directories "plate-3xxx-3xxx" that contain hundreds of g=25 or g<0 magnitudes, the result follows: ------------------------------------------------------------------- N_bad_stars File Plug status ------------------------------------------------------------------- 592 plate-3100-3120/plPlugMapP-3102.par N/A 592 plate-3100-3120/plPlugMapP-3111.par available to plug 592 plate-3100-3120/plPlugMapP-3113.par N/A 592 plate-3100-3120/plPlugMapP-3116.par plugged 592 plate-3100-3120/plPlugMapP-3117.par N/A 592 plate-3100-3120/plPlugMapP-3118.par N/A 592 plate-3100-3120/plPlugMapP-3120.par N/A One plate is available to plug (3111), we should avoid plugging it until the magnitudes are fixed.
