The bad pixel image is of pixel type short and +has the value given by the parameter \fBgoodvalue\fR for the good +pixels and the value given by the parameter \fBbadvalue\fR for the bad pixels. +The image size and header parameters are taken from the specified +template image. The bad pixel mask image may be used to view the +location of the bad pixels and blink against an data image using an +image display, to mask or flag bad pixels later by image arithmetic, +and to propagate the positions of the bad pixels through the +reductions. +.ih +EXAMPLES +1.
