Cosmic ray detection was performed in stacks with the same dither position. ... At each pixel CRREJ looks at the stack of frames and selects some initial pixel value, which can be the minimum or the median across the stack. ... For these suspect pixels, the thresholds are multiplied by a parameter PFAC which can be anything from zero, meaning that all suspects are automatically rejected, to one. ... The pixel values for pixels thrown out by a PFAC=0 choice, but not by PFAC=0.5 choice were compared. ...

The determination of the detector parameters is based on sets of images of a spatially uniform-illumination scene (flatfield frames) and without any illumination (dark frames), putting a plug in place of the filter, taken at a series of exposure times. ... We interleave before and after each exposure time in the series of flatfield frames a set of reference images at an exposure time of 1 sec to determine the possible temporal variation of the illumination level. ...

... When creating a mosaic from a set of individual frames, the correct background offset for each frame must be determined for proper matching. In this paper we describe a method for constructing a mosaic from a set of individual frames by applying a minimization technique. ... Typically these are frames with some known defect (see ? ... Determining which frames to exclude from the final mosaic is critical, since one bad frame can create background offset errors that propagate throughout the mosaic. ...
