Astro::Hipparcos::Record - Represents a single Hipparcos record



  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


Represents a single Hipparcos record. The code is auto-generated from the C-level structure. Thus the funny member names.



Returns a new record object.


Somewhat internal method that may SEGFAULT if you use it wrong.

Given a string that MUST contain a full line from the record file, fills the object with data from that line.


Returns the full original catalog line.


Each of these methods descriptions have the following format:
