CCD: FULL 13'x13' armin READOUT: ONE AMP GAIN INDEX: 3: Read Noise ~ 3.5 ADU = 3.5 e- FILTER SET: UBVRI (using R filter only) ----------------------------------------------------------------------- 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. ----------------------------------------------------------------------- OBSERVING SEQUENCE ----------------------------------------------------------------------- KBO #exposures Total time Priority x seconds for object each night 55636 5x600sec (60 minutes) 3 Eris 4x600sec (50 minutes) 2 55638 5x600sec (60 minutes) 2 Varuna 5x600sec (60 minutes) 1 Field_Var20081207 4x40sec (10 minutes) 1 Orcus 5x600sec (60 minutes) 2 Priority: 1=Highest, 2=Medium, 3=Low Please image all objects listed for the required time.
