Astro::Hipparcos - Perl extension for reading the Hipparcos star catalog
use Astro::Hipparcos; my $catalog = Astro::Hipparcos->new("thefile.dat"); while (defined(my $record = $catalog->get_record())) { print $record->get_HIP(), "\n"; # print record id } # the twelth record (i.e. first is 1, NOT 0) my $specific_record = $catalog->get_record(12);
This is an extension for reading the Hipparcos star catalog.
Given a file name, returns a new Astro::Hipparcos catalog object.
Returns the next record (line) from the catalog as an Astro::Hipparcos::Record object.
Appends a record to an existing (or new) catalog. Can be used to select subsamples of the full record and write them to new data files. Confer the example in this distribution examples/simple_selection.pl.
For an example what you can produce with this little tool, have a look at http://steffen-mueller.net/hipparcos/hipparcos.eps.bz2. This is implemented in the examples/draw_hammer_proj.pl example in this distribution.
