CSIRO’s Data Access Portal contains the most comprehensive archive of pulsar data globally, with over 4 Petabytes from Murriyang, the CSIRO Parkes radio telescope available for download. The DAP is Virtual Observatory compatible and can be queried using VO tools such as TOPCAT . The TOPCAT image above is a Hammer-Aitoff projection in Galactic coordinates of the published observations from the MEDUSA Parkes pulsar backend for the 2024APR semester (the period 1 April 2024 to 30 September 2024). Approximately 2-3TB of new pulsar data are added to the archive each day. Access to new data is restricted to project teams during the statutory 18-month embargo period, thereafter the data become public.
