REMDBM - Remove dual beam signature from scan maps

Description:

This program should be used to reduce SCAN/MAP data taken using the technique described by Emerson (1995, ASP Conf Ser 75, 309). The deconvolution is performed using Fast Fourier techniques.

Usage:

remdbm [-h] [-v] [-out=] [-noams] [-filter] files

Parameters:

$-$h

Help message

$-$v

Version number. Also indicates whether ADAM communication is enabled.

$-$out=file

Filename of output image. Default is `final.sdf'

$-$noams

Turn off ADAM messaging if available. Default is false. Ignored if ADAM messaging is not available.

$-$filter

Turns on high frequency filtering. When used, data at frequencies greater than that to which the telescope is sensitive are set to zero.

files

List of input files to be processed. Shell wildcards are allowed. See notes for restrictions.

Examples:

remdbm $*$_reb.sdf

Process all files matching the pattern and write the result to final.sdf.

remdbm -out=m82 o66_lon_reb o67_lon_reb o68_lon_reb o69_lon_reb

Process the four input images. The output filename is set to m82.sdf.

remdbm -filter -noams *_reb.sdf

Process the supplied files with high frequency filtering. Do not use the messaging system.

Notes:

The following restrictions apply:

• Each image should contain a single chop configuration.

• Each image must have identical dimensions and pixel size (they do not need to be square)

• The images must be rebinned in the same coordinate system as the chop throw.
