The pulsar catalog consists of a primary FITS file containing information about all 117 pulsars. In addition, there will be ancillary FITS files, one per pulsar, containing contain the lightcurve, spectrum, and timing information.

These file definitions will also include Unified Content Descriptors metadata to keep the file VO-compliant. You can find the list of accepted UCD indicators here.

...

The tarball of files containing the pulsar catalog results and associated files released with the paper will includeincludes:

  1. Pulsar Catalog FITS file
  2. Directory containing PDF spectral plots
  3. Directory containing 117 PDF lightcurve plots
  4. Directory containing timing par files
  5. Directory containing individual pulsar FITS file
