GCVS checking script

[Michael Koppelman <lolife@bitstream.net>]

OK, here's my first draft at a script to check stars against the GCVS. So
far all it does it check the GCVS, it does not check the NSV or SIMBAD in
general. It's a bit of a hack in that it does an HTTP POST to VizieR and
parses the results. I've attached it. Make sure to check that it has proper
new lines on your system and check the perl path. You need the CGI and LWP
perl modules to use it. I've included comments that tell the basics of using
it.

The gist of it is, you can run it as a one-liner like this:

digital [8:47pm] % cat collected.big | ./wsv3.pl | awk '{ print $1, $4, $5
}' | ./check_stars.pl
Match for 2 at RA=61.7727 DEC=+6.2965:  XY    Tau
No match for 11 at RA=61.8053 DEC=+7.1258:
No match for 16 at RA=61.8132 DEC=+6.3626:
No match for 23 at RA=61.8235 DEC=+7.5687:
No match for 24 at RA=61.8273 DEC=+7.7068:


I reverse sorted the output of wsv3.pl by the ws statistic and when I run it
on that file I get:

digital [8:49pm] % cat mystars.tab | awk '{ print $1, $4, $5 }' |
./check_stars.pl

The vast majority of stars with a WS value > 1 are not in the GCVS. There
are many stars with very high WS values that are not in the GCVS. I know
that doesn't necessarily mean they are variable but encouraging nonetheless.

Let me know your thoughts.
