I am currently writing a proposal for a NASA ROSES 2024 call for Roman-related projects. The idea is to extend the UK In-Kind Contribution by providing person-power to create Roman and Rubin cross-match catalogue. I think such catalogue should be available through Rubin Science Platform and the planned NASA services. NASA requires that data products made possible through NASA funding be available to the wider public. However, there is a problem of Rubin data rights. The cross-match catalogue could be hosted on Rubin Science Platform and not break any policies on the Rubin side of things. I am wondering if a limited version of such catalogue should be available through the Roman Science Platform. A full table hosted by Rubin SP would contain: Rubin source ID, Roman source ID, coordinates from both catalogues, and magnitudes from both catalogues in all available bands.
A limited table hosted by Roman SP would contain only Roman and Rubin source IDs, and maybe coordinates and magnitudes for Roman. Then I could provide examples with queries to the Rubin data services to get the rest of the data for people with data rights.
My question is is the Rubin source ID a data category that can be provided outside of the Rubin Science Platform? If not, could someone help me create a justification for why such catalogue could be hosted only on the Rubin Science Platform?
An additional question is about what are plans for hosting Rubin Science Platform or Rubin data products after the end of the 10 years of the survey? Would it be possible to move a cross-match catalogue to a service such as NASA’s MAST?
