Gaia Sprints

2019 Santa Barbara Gaia Sprint

This page preserves the history from the 2019 Santa Barbara Gaia Sprint, which took place 2019 March 25 through 29 at the Kavli Institute for Theoretical Physics.

Results

On the first day, all participants presented a slide from the jointly edited 2019 Santa Barbara Gaia Sprint Pitch Slides to introduce themselves, their skills, expertise, and their ideas for the week.

Before and during the meeting, we kept jointly edited 2019 Santa Barbara Gaia Sprint Running Notes that gathered information about homework solutions, intended projects, and breakouts.

On the last day, the wrap up was given from a jointly edited set of 2019 Santa Barbara Gaia Sprint Wrap-up Slides, which summarize the accomplishments made throughout the week.

Objectives

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.

Collaboration Policy

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.
