Hi @punyakoti, thank you for these questions, I’m happy to answer them for you.
- Yes, the Google form is the only step of the DP0 application process.
- The DP0 data set is a subset of the DC2 simulation – I have linked to two other posts below that describe the DP0 data set in more detail.
- The DC2 catalogs are publicly available, yes – but the advantage of DP0 participation is use of the Rubin Science Platform for data access and analysis.
- Unfortunately the Rubin Observatory cannot accommodate all members of the Science Collaborations as DP0 participants.
