lcplot – a program to plot light curves of variable stars

About

lcplot is a command-line program that plots light curves of variable stars using data from the American Association of Variable Star Observers (AAVSO).

lcplot is written in Perl 5. Apart from the Perl executable, lcplot also needs the Perl modules DateTime, Astro::Time, and LWP::Simple, and gnuplot as plotting engine.

USAGE

To plot visual estimates and V band observations for a star during the last N days use:

lcplot.pl STAR CONSTELLATION NDAYS

To optionally highlight observations done by OBSERVER.

lcplot.pl STAR CONSTELLATION NDAYS OBSERVER

where OBSERVER is the AAVSO observer code

In both cases the result is a PNG file with the plot.

EXAMPLE:

This will plot the last 200 days of observations for khi Cygni, without highlighting any observer:

lcplot.pl khi Cyg 200

It will produce a PNG image with name "Cyg-khi.png".

If we add to the same line an AAVSO observer code, for example, "OBS":

lcplot.pl khi Cyg 200 OBS

It will higlight observations contributed by observer OBS using blue crosses.
