The ATNF Pulsar Catalogue, edited by F. Camilo and B. M. Gaensler, presents an updated list of known pulsars, reflecting significant increases in discoveries over recent years. The catalogue includes all rotation-powered pulsars, such as anomalous X-ray pulsars (AXPs) and soft gamma-ray repeaters (SGRs), with coherent pulsations detected. It excludes accretion-powered pulsars like Her X-1 and X-ray millisecond pulsars. The catalogue contains information on 1300 pulsars, with up to 90 parameters recorded for each, including names, positions, rotational frequencies, and types. Additional parameters such as higher-order rotational frequency derivatives, pulse widths, orbital parameters, and associations with globular clusters or supernova remnants are also included. Derived parameters, calculated from available data, are also available. The catalogue is accessible via a web interface or command-line interface. The web interface allows users to select parameters, generate custom variables, and display data in various formats, including graphical plots and histograms. An 'expert-mode' allows users to upload personal catalogues or merge them with the public one. The command-line interface provides similar functionality to the web interface but lacks plotting routines. The software is available for Solaris and Linux systems via anonymous FTP. The work makes extensive use of NASA's Astrophysics Data System and SLALIB C routines. The authors thank several individuals for their contributions to the database's maintenance and development.The ATNF Pulsar Catalogue, edited by F. Camilo and B. M.
