RESTORE - 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 $\backslash$

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).
