visual - Compare Celestrak visual to McCants vsnames
visual visual -help visual -version
If asserted, this Boolean option causes debug information to be written to standard error. Asserting this option is unsupported, at least in the sense that the author reserves the right to change the output without notice.
If this Boolean option is asserted, Astro::SpaceTrack and JSON are loaded, and the Space Track web site is queried for the Satcat status of the objects. Any that have defined decay dates are eliminated.
This option displays the documentation for this script. The script then exits.
If asserted, this option causes Mike McCants' quicksat.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 quicksat list. The output is Data::Dumper format.
This option displays the version of this script. The script then exits.
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
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.
