----------------------------------------------------------------------- INSTRUMENT SETUP 2012B SHEPPARD - 05 SEPT 2012 - CTIO 0.9m queue observing ----------------------------------------------------------------------- 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 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 2003MW12 5x600sec (75 minutes) 1 2003MW1220130113 5x200sec (30 minutes) 1 2003MW1220130601 5x150sec (30 minutes) 1 2002MS4 5x600sec (75 minutes) 1 Pluto 12x40sec (60 minutes) 1 P20130504 5x45sec (30 minutes) 2 P20130607 5x45sec (30 minutes) 2 P20140731 5x15sec (20 minutes) 2 2004NT33 5x600sec (75 minutes) 1 2004NT33_2013060ff 5x120sec (30 minutes) 1 120178_20121227 5x45sec (30 minutes) 2 120178_20130831 5x300sec (40 minutes) 2 145452 5x600sec (75 minutes) 1 Priority: 1=Highest, 2=Medium, 3=Low R-band filter for all observations.
