Assumptions

The roadmap is based on the schedule of data-product publication issued by the Rubin Observatory project (Rubin Observatory Plans for an Early Science Program (Leanne Guy et al. RTN-11)) as at June 2023.
Intregration of Lasair services into the DAC is in development. Lasair services will be added to the roadmap once they are confirmed.
Timeline for switching to the Project-recommended user authentication mechanism is dependent on relevant RSP components being confirmed to be sufficiently mature.
