SRCAST

Name

srcast

Purpose

Compute ra,dec for all objects in a source list (see findsrc).

Description

Calling Sequence

srcast,file

Inputs

file - File(s) to be read and have ra,dec computed. The file names are
expected to end in .src (usually generated by findsrc).

Optional Input Parameters

Keyword Input Parameters

DIR - Directory where .src files are to be found and where .srd files
will be written.
OVERWRITE - Flag, if not set this program will skip any files that already
have the .srd output file. Set this to overwrite and
regenerate those files.

Outputs

A file is written, the name of the file is the same as the input except
that the final suffix is changed from .src to .srd. The output file
is a FITS format file which is basically a table of numbers. [nobjs,9]
The contents are as follows:
Row Contents
0 Raw x coordinate of object
1 Raw y coordinate of object
2 FWHM of object
3 Raw instrumental magnitude of object
4 Uncertainty on the instrumental magnitude
5 RA of object, J2000
6 Dec of object, J2000
7 signal-to-noise ratio of object
8 Standard magnitude for object.
Rows 0-4 and 7 are carried forward from the .src file with no change.
The new columns are computed from the astrometric solution for this frame.

Procedure

An optional file, badframes, can be used to skip images that are bad.
If it exists, it must contain the file names (no path) of the image(s)
to be skipped. This file is expected to be in the current directory.
