Overview

The Australia Telescope National Facility (ATNF) Pulsar Catalog is a catalog of known pulsars compiled by R.N. Manchester et al. and is descended from pulsar database used for the paper "Catalog of 558 Pulsars" by J.H. Taylor, R.N. Manchester and A.G. Lyne 1993, ApJS, 88, 529-568. The current catalog has been supplemented by inclusion of published data from more recent radio surveys, in particular, the Parkes Multibeam (PM) Pulsar Survey (Manchester et al. 2001, MNRAS, 328, 17-35) [available at the HEASARC as the PMPULSAR table] and the Swinburne Intermediate Latitude Pulsar Survey (Edwards et al. 2001, MNRAS, 326, 358-374), both made using the ATNF Parkes 64-m radio telescope. Binary parameters for known binary pulsars are also included as well as all available astrometric and spin parameter information for all pulsars. The catalog includes all published rotation-powered pulsars. Two separate small subsets of pulsars detected only at high energies are also included in the current table: the first group comprises X-ray and gamma-ray pulsars which are apparently powered by spin-down energy, but which have not been detected at radio wavelengths, while the second group contains anomalous X-ray pulsars (AXPs) and soft-gamma-ray repeaters (SGRs) for which coherent pulsations have been detected. Accretion-powered pulsars such as Her X-1 and the recently discovered X-ray millisecond pulsars such as SAX J1808.4-3658 are not included in this table, however.

Many people have contributed to the compilation of the data contained in this catalog and the database that it was derived from. The authors particularly thank Andrew Lyne of the University of Manchester, Jodrell Bank Observatory, David Nice of Princeton University, and Russell Edwards, then at Swinburne University of Technology. The also acknowledge the efforts of Warwick University students Adam Goode and Steven Thomas who compiled and checked a recent version of the database. The original (summer 2003) database at the ATNF website was compiled with the invaluable assistance of Maryam Hobbs, while the ATNF web interface was designed and constructed by Albert Teoh, a Summer Vacation Scholar at the ATNF in 2002/2003.

The authors would appreciate if anyone making use of this catalog in a publication acknowledges the source of their information by quoting the ATNF Pulsar Catalog website address of http://www.atnf.csiro.au/research/pulsar/psrcat/

Provenance

This database table was initially created by the HEASARC in January 2002. It was revised in March 2002, in June 2003, and again in January 2014. It is based on the table obtained from http://www.atnf.csiro.au/research/pulsar/psrcat/expert.html.

Changes to the catalog are logged at http://www.atnf.csiro.au/research/pulsar/psrcat/catalogueHistory.html.

The HEASARC table will be updated on a weekly basis whenever the original ATNF database table is updated.


Parameters

Name
The name of the pulsar using the standard designation for pulsars, based on its J2000 coordinates.

Alt_Name

RA

The RA is given in J2000 coordinates and to various precisions in the original ATNF table, ranging from 1.0E-08 seconds of time to 1 minute of time. The HEASARC Browse system's built-in precession routines are not of astrometric accuracy, and thus we recommend using the default J2000 equinox for positions when querying this database. Even then, the Right Ascensions in this HEASARC table are displayed only up to a precision of 0.0001 seconds of time; for those specialized applications where a higher positional accuracy is desired, users should consult the original version of these data at the ATNF Pulsar Group website, http://www.atnf.csiro.au/research/pulsar/psrcat/.
