CSIRO’s CSIRO’s Data Access Portal contains the most comprehensive archive of pulsar data globally, with over 4.5 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. This TOPCAT image is a Hammer-Aitoff projection in Galactic coordinates of the published observations from the Apollo pulsar backend for the 2025OCT semester (the period October 1st 2025 to March 31st 2026). Approximately 2-3 TB 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.
