The aim of this workshop is to prepare for the exploitation of Gaia data, the first release of which is now due in late 2015. The format, as previously, is that participants are invited to apply their favorite techniques to mock data in an effort to recover underlying physical quantities, like the gravitational potential and the phase-space structure of stars. The mock data will be distributed in advance, and the workshop itself is focused on comparing and discussing results, honing the various techniques, and building collaborations. The challenges are divided into five broad categories. Four of these continue from the first workshop, held in Surrey, UK last year, but with mock datasets that are more realistic with the addition of Gaia-type errors. A new, fifth module, concentrating on the recovery of astrophysical parameters is being added.

The five modules with their current coordinators are:

  1. Spherical & Triaxial (Justin Read, AT
  2. Discs (Daisuke Kawata, d.kawata AT
  3. Streams & Halo Stars (Andreea Font, A.S.Font AT & Andreas Kuepper, ahwkuepper AT
  4. Collisional Systems (Mark Gieles, m.gieles AT & Vincent Henault-Brunet v.henault-brunet AT
  5. Astrophysical Parameters (Rene Andrae. andrae AT & Kester Smith, smith AT

Most of the time during the week is dedicated to working on the challenges in groups of 10-20 people per module.
