FLATFIELD - Flatfield demodulated SCUBA data

Description:
This routine flatfields SCUBA demodulated data. The data must previously have been processed by reduce_switch.

Usage:
flatfield in out

Parameters:

IN = NDF (Read)
The name of the NDF containing the demodulated data to be flatfielded. This file should already have been run through the reduce_switch application.
MSG_FILTER = CHAR (Read)
Message filter level. Allowed values are QUIET, NORM and VERB. Default is NORM. There are no verbose messages.
