DICTIONARY VIRCAM_PIPE "VIRCAM" "VISTA IR Camera Instrument reduction keywords" REVISION "$Revision: 0.5 $" CONTEXT "FITS" RECIPE %s Data-reduction recipe to be used (h). Name of data-reduction procedure expected to be used with this exposure. OFFSTNUM %d Value of first OBSNUM in current tile sequence (h). OBSNUM %d Observation Number (h). An incremental count of observations starting from day 1. A co-add performed in the data-acquisition system counts as a single observation. GRPNUM %d Group number applied to all members (h). GRPMEM %c Group membership (h). Group membership truth value. STANDARD %c Standard-star observation (h). True if observation is of a standard star, or standard field. NOFFSETS %d Number of offset positions in a field (h). OFFSET_I %d Serial Number of offset (h). To keep track of which part of a pointing we are on. NJITTER %d Number of positions in a tel jitter pattern (h). Number of positions in a telescope jitter pattern JITTRNUM %d Value of first OBSNUM in current jitter sequence (h). JITTER_I %d Serial number of this tel jitter pattern (h). Serial number of this telescope jitter pattern. JITTER_X %.3f X offset in jitter pattern [arcsec] (h). X offset in jitter is approximately aligned with RA and measured east along a great circle from the starting point. JITTER_Y %.3f Y offset in jitter pattern [arcsec] (h). Y offset in jitter is approximately aligned North (but there is no reason why one might jitter through the South Celestial Pole) and measured along a great circle from the starting point. NUSTEP %d Number of positions in microstep pattern (h). USTEPNUM %d Value of first OBSNUM in current microstep sequence (h). USTEP_I %d Serial number of microstep pattern (h). USTEP_X %.3f X offset in microstep pattern [arcsec] (h). X offset in microstep is approximately aligned with RA and measured east along a great circle from the starting point. USTEP_Y %.3f Y offset in microstep pattern [arcsec] (h). X offset in microstep is approximately aligned North and measured along a great circle from the starting point.
