TITLE

visual - Compare Celestrak visual to McCants vsnames

SYNOPSIS

 visual
 visual -help
 visual -version

OPTIONS

-help

This option displays the documentation for this script. The script then exits.

-merge

If asserted, this option causes Mike McCants' mcnames.mag file to be fetched also, and a magnitude hash to be produced that defines magnitudes for any body that appears on either the Celestrak visual list or the McCants vsnames list, and has a magnitude in either the McCants vsnames list or the McCants mcnames list. The output is Data::Dumper format.

-version

This option displays the version of this script. The script then exits.

DETAILS

This Perl script downloads the list of visual bodies from the Celestrak web site and the vsnames.mag file from Mike McCants' web site and compares the two, reporting OIDs that are not on both sites and what site they are on.

Note, though, that you get different output if you assert -merge.

In either case, though, the last thing you get is a Last-Modified: date, which is the most-recent of any of the data sources examined.
