REFEXT

Name

refext

Purpose

Batch mode extraction of REFNET star catalog fields in support of ASTROM

Description

Calling Sequence

refext,root,startnum,finnum

Inputs

startnum - First frame number to process
finnum - Last frame number to process

Optional Input Parameters

Keyword Input Parameters

CATPAD - Amount of extra padding for catalog extraction in arcsec. The
default is zero.
EXTLIST - If image is a multi-extension FITS image, this list will
force the reduction of only the extension numbers listed.
The default is to do all the extensions, one at a time.
KEYLIST - Name of a file containing a correspondence list. This list
associates a set of standard names with the actual keyword
names found in a FITS file header. If this keyword is
omitted, a default list is used, as if a file with the
following contents had been supplied:
AIRMASS K AIRMASS
DATE K DATE-OBS
DATETMPL T DD-MM-YYYY
EXPDELTA V 0.0
EXPTIME K EXPTIME
FILTER K FILTERS
FILENAME K CCDFNAME
* OBJECT K OBJECT
UT K UT
* RA K RA
* DEC K DEC
* EPOCH K EPOCH
The middle column is a flag. It may be K, for Keyword,
T, for Template, or V, for Value. If it is V, the contents
of the third field on that line should make sense for the
name in the first field. Only those fields marked with '*'
are actually used by this program.
MAGLIM - Limiting (faint) magnitude for catalog extraction (default=30.0)
NODOT - Flag, if set suppresses inserting a . in the file name
PATH - String, this is the name of the directory where the data are
stored. The actual data directory used is PATH+'/'+root.
The default is '' (blank) and the file would be root.NNN
which would permit putting a leading path on the root.
PSCALE - Scalar number, this is the scale of the image in arcsec/pixel.
If not specified, then this program will look for the
ASTROM information file, astrom.inf, in the current directory
for the plate scale. If the file does not exist, then you
will be prompted to provide the plate scale directly.
SCRIPT - String, if provided is the file name to save a script to.
If set will suppress the actual call to refnet to
generate the star sub-catalogs. Instead, all the calls
to refnet will be saved to this file.
NOBINARY - Flag, if set will suppress automatically promoting the ASCII
catalog files to the binary format.
