remove the chopped beam response from SCAN/MAP observations

Description:

This routine removes the chopped beam response from SCAN/MAP observations.

Usage:

restore in out chop

Parameters:

CHOP = INTEGER (Read)
Chop throw in arcseconds. The default chop throw is read from the FITS header of the input file.
IN = NDF (Read)
The name of the input file containing demodulated SCUBA data.
MSG_FILTER = CHAR (Read)
Message filter level. Allowed values are QUIET, NORM and VERB. Default is NORM. There are no verbose messages.
OUT = NDF (Write)
The name of the output file to contain the processed data.

Examples:

restore input output
Restore input.sdf to output.sdf using the default chop throw.
restore resw restore 40.2
Restore resw.sdf to restore.sdf using a chop throw of 40.2 arcseconds.

Notes:

Uses the Emerson, Klein and Haslam algorithm (1979, A&A, 76, 92).

This routine can only be used on SCAN/MAP data taken whilst chopping along the scan direction (CHOP_COORDS=SC).
