App::SourcePlot
===============

Source Plot was created to help observers decide which sources to observe
at particular times to optimize the observing time at the telescope.
The main purpose of this program is to plot the movement of a source
throughout the night.  The movement can be plotted by the source's
elevation, azimuth, parallactic angle, or by time.

This application was originally written by Casey Best <cbest@uvic.ca> and
Pam Shimek <pshimek@uvic.ca>.   It also includes patches by Remo Tilanus
<r.tilanus@jach.hawaii.edu> and Tim Jenness <tjenness@cpan.org>.  For
version 1.17 it was updated to use the Astro::Coords and Astro::Catalog
modules by Graham Bell <g.bell@jach.hawaii.edu>.

It is currently supported by Graham Bell <g.bell@jach.hawaii.edu>.
