Access to ASKAP data

CASDA has now returned to normal service.

Data from CSIRO’s ASKAP telescope on Wajarri Country is transferred to the Pawsey Supercomputing Research Centre, processed on the Setonix supercomputer, and then archived on Pawsey’s Acacia Ingest cluster. This data is then made available to researchers via the CASDA archive on CSIRO’s Data Access Portal.

From 22 January 2024 Pawsey’s Acacia Ingest system was unavailable. During this outage data was deposited into a temporary workflow into CASDA from 6 February 2024.

Acacia Ingest was returned to service on 16 February and the normal workflow resumed. However, data deposited during the temporary workflow between 6 and 16 February was unavailable while they were migrated back to the original storage.

This migration is now complete and CASDA has been restored to normal service.

We are grateful for your understanding and apologise for the inconvenience caused by this disruption.

The CSIRO ASKAP Science Data Archive (CASDA) is making data from Australia’s SKA Pathfinder (ASKAP) telescope available to the astronomical community.

Raw data from the ASKAP observatory is processed by software custom-built by CSIRO (ASKAPsoft) into science ready images, cubes and catalogues. These data products are then made accessible by CASDA via a web UI (CSIRO Data Access Portal) and Virtual Observatory services.

CASDA is a collaboration between CSIRO and the Pawsey Supercomputing Centre.
