USAGE

adjust-mask -o observset -f framename  [-d newdef]

INPUT

framename is a set of image files containing a direct or dispersed image of a slitmask. observset.obsdef is the name of an existing observation definition file which describes the observing setup used for the frame and specifies an existing dewar offset file . newdef.dewoff is an optional name for the new dewar offset file.
