REFNET

Name

refnet

Purpose

Support routine for calling ``REFNET'' to get stars from master catalogs.

Description

Calling Sequence

refnet,ra,dec,width,height,bmaglim,rmaglim,starfile

Inputs

ra - Right ascension of center of field for extraction (J2000)
input can be in radians (double,float) or
a string HH:MM:SS.S (see RAPARSE for valid syntax).
dec - Declination of center of field for extraction (J2000, radians).
input can be in radians (double,float) or
a string +DD:MM:SS.S (see DECPARSE for valid syntax).
width - Width of field to extract (arcsec).
height - Height of field to extract (arcsec).
bmaglim - Limiting Blue magnitude to extract.
rmaglim - Limiting Red magnitude to extract.
starfile- File name for the results of the catalog extraction.

Optional Input Parameters

Keyword Input Parameters

TWOMASS - String. Set to 'J', 'H', or 'K' to request 2MASS point-source
catalog data in that filter.

Outputs

The output is all to the file and contains a list of stars from the
USNO A2.0 catalog according to the input constraints.

Keyword Output Parameters

Common Blocks

Side Effects

Restrictions

Currently this is rather restricted and is just an initial working version.
This is hardcoded to a specific location for the catalog and executable.
This program will work only on Unix platforms at present.
You must define an evironment variable, USNO_CAT, that points to the
directory where the data live. Default is the current directory.
