The Gaia team have announced plans to make Early Data Release 3 (EDR3) publicly available on 2020 December 03. This data release will use make use of 34 months of Gaia data, compared to 22 months of data that made up DR2. The longer observing baseline is expected to provide an improvement in mean parallax precision of about 20%, and improve the proper motion precision by a factor of two. EDR3 will also benefit from an improved understanding of outliers, redundancies, and flagging, providing a cleaner data set.
The 2020 EDR3 Unboxing Gaia Sprint will take place on 2020 December 03 - 2020 December 04 to coincide with the anticipated release of EDR3 on 2020 December 03. Details on how to sign-up for the 2020 EDR3 Unboxing Gaia Sprint will be posted here.
The idea behind the Sprints is to bring together people who have an interest in timely scientific investigation and use of the Gaia Data. These are not traditional scientific meetings; they are intended to facilitate completion of first scientific papers. The Sprints are structured to support collaborative refinement and execution of (fairly) mature scientific ideas. It is hoped that new partnerships will form and lead to co-authored publications for the scientific literature ready or near-ready by the end of each Sprint.
In addition to a general Code of Conduct, we require participants to agree to a Collaboration Policy that ensures transparency and openness at the Sprints:
All participants at every Gaia Sprint will be expected to openly share their ideas, expertise, code, and interim results. Project development will proceed out in the open, among participants and in the world.
Participants will be encouraged to change gears, start new collaborations, and combine projects. Any participant who contributes significantly to a project can expect co-authorship on resulting scientific papers, and any participant who gets signficant contributions to a project is expected to include those contributors as co-authors.
These rules make it inadvisable to bring proprietary data sets or proprietary code to any Sprint, unless the participant bringing such assets has the rights to open them or add collaborators.
