----------------------------------------------------------------------- INSTRUMENT SETUP 2012A ----------------------------------------------------------------------- CONDITIONS: ANY CCD: FULL 13.7'x13.7' READOUT: ONE AMP GAIN INDEX: 3: Read Noise ~ 1.7 ADU = 3.1 e- FILTER SET: UBVRI CALIBRATION FRAMES: BIAS - 10 DOME FLAT R 10 ~20000 counts ----------------------------------------------------------------------- NOTES FOR TARGET FIELDS ----------------------------------------------------------------------- Our program is to observe bright Kuiper Belt objects (KBOs) to 0.01 arcsecond precision in order to obtain very precise astrometry. Some objects can only be observed at the very beginning or end of the night. The observations are simple direct imaging mostly in the R-band. Images of the KBOs should be no more than about 10 minutes each to prevent trailing losses of the moving KBOs. 15 arcsecond dithering between successive images is requested. ----------------------------------------------------------------------- NOTES FOR CALIBRATION FIELDS ----------------------------------------------------------------------- No standards are needed. Only flats and biases are needed in the R-band. Epoch is J2000 ----------------------------------------------------------------------- OBSERVING SEQUENCE ----------------------------------------------------------------------- KBO or Field #exposures Total time Priority x seconds 55565 4x600sec (60 minutes) 3 Orcus 4x600sec (60 minutes) 3 26375 4x600sec (60 minutes) 2 90568 4x600sec (60 minutes) 3 119951 4x600sec (60 minutes) 2 Ixion 5x600sec (80 minutes) 2 Quaoar 4x600sec (60 minutes) 2 2003MW12_20130113 5x180sec (40 minutes) 1 2003MW12_20130226 5x180sec (40 minutes) 1 120178_20120711 4x140sec (30 minutes) 1 120178_20121227 4x45sec (30 minutes) 1 Chiron 4x400sec (40 minutes) 1 Priority: 1=Highest, 2=Medium, 3=Low The proper J2000 RA and Dec for each KBO for early May 2012 is put below.
