Gaia Data Release Scenario - Gaia
Gaia Data Release scenario
On this webpage, the target release scenario is presented, based on the current status of processing.
Photometric and new asteroid science alerts are already being issued.
In general, individual epoch observations and transits will be released only with the final catalogue. However, when variable star solutions, etc. are released, relevant subsets of epoch data may also be released. Additionally, where the release of epoch data is of immediate scientific interest, such release will be made on an individual source-by-source basis through the science alerts.
After production of the catalogue for release, a validation exercise will be executed. The final, detailed release contents will be decided on only after completion of the validation work.
The third release is composed of Gaia Early Data Release 3 (Gaia EDR3), released in 2020 and the full Gaia Data Release 3 (Gaia DR3), expected in 2022.
