The ATNF Pulsar Catalogue, developed by G. Hobbs, R. Manchester, A. Teoh, and M. Hobbs from the Australia Telescope National Facility (ATNF), is a comprehensive database of rotation-powered pulsars, including high-energy pulsars, anomalous X-ray pulsars (AXPs), and soft gamma-ray repeaters (SGRs). The catalogue, accessible via a web interface or command-line interface, contains detailed information on 1300 pulsars, including up to 90 different parameters such as names, positions, rotational frequencies, and derived parameters. The web interface allows users to select parameters, generate custom variables, and display results in various formats, including graphical plots and histograms. An expert mode is available for specialized users to access more detailed parameters and upload personal catalogues. The command-line interface, tested on Solaris and Linux, provides similar functionality except for plotting routines. The catalogue has been significantly contributed to by various researchers and has utilized NASA’s Astrophysics Data System and SLALIB C routines.The ATNF Pulsar Catalogue, developed by G. Hobbs, R.
