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.
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,
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.

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.
We ask that any publications that were started or worked on
during this Gaia Sprint include the following acknowledgements:
This project was developed in part at the 2019 Santa Barbara Gaia Sprint, hosted by the Kavli Institute for Theoretical Physics at the University of California, Santa Barbara.
This research was supported in part at KITP by the Heising-Simons Foundation and the National Science Foundation under Grant No. NSF PHY-1748958.
These sentences do not need to be adjacent in your acknowledgements.
In addition, please make sure that you properly acknowledge the Gaia
and DPAC teams, in according with their
credit and citation instructions.
