----------------------------------------------------------------------- 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 ---- Full Night April 12 ---- (Night 1) 55565 5x600sec (75 minutes) 2 Orcus 5x600sec (75 minutes) 1 90568 5x600sec (75 minutes) 1 Haumea 3x600sec (45 minutes) 3 Quaoar_20120710 4x180sec (30 minutes) 2 2003MW12_20130113 5x180sec (40 minutes) 1 2003MW12_20130226 5x180sec (40 minutes) 1 2002MS4 5x600sec (75 minutes) 2 120178_20120711 5x180sec (40 minutes) 1 120178 4x600sec (60 minutes) 1 Priority: 1=Highest, 2=Medium, 3=Low The proper J2000 RA and Dec for each KBO for April 2012 is put below.
