Our current [draft] publication plan/policy for the Gaia challenge test data is as follows:

• Each of the main test suites will be published separately (3-4 papers), including a description of the test data and the results from the different techniques. There will be a strict deadline for the paper (to be decided); only participants who have completed the tests in time will be included. The lead author for each paper will need to be decided by each test sub-group, but should be the person who is leading that particular test. Co-authorship will be granted to anyone who has participated in running or setting up the test(s), and to the Gaia Challenge main coordinators.
• Future publications can freely use the Gaia Challenge data products, but must reference this wiki (from where the data is downloaded) and the relevant test paper(s).
• Any improvements or amendments to Gaia challenge tests that use or build on Gaia challenge data products must be made available to the community through this wiki.
