Benefit hypothesis:

Hide

SRCs will provide pre-built scripts for standard workflows that users expect to run. We aim to implement some of these, and test their effectiveness with regards to hardware limitations and data storage schemes.

This particular workflow looks at crossmatching different catalogues. This will be a common workflow users will run to compare SKA data with other telescopes. In some cases users will want to crossmatch entire surveys, and data will be distributed in some way. Users will want to either have other survey catalogues readily available at SRC nodes, or will want to download other catalogues so they can perform crossmatching with SKA data.

Acceptance criteria:

Hide

AC1: Implement a basic crossmatching script that can combine multi-wavelength catalogues with some user defined criteria such as matching radius.

AC2: Get the workflow to pull LOFAR and SDSS/PanStarrs catalogues to cross-match.

AC3: Document this on the workflow Gitlab repo and record a demo.
