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).
