Status of the partners preparing for the Gaia Alerts verification

Information about the requirements

In order to become a member of the Gaia Follow-up Network for Transient Objects (Gaia-FUN-TO), especially to take part in the alerts verification, a potential partner must fullfil a number of requirements. The list of requirements is still to be fine-tuned, but they are:

  1. react to an alert (or to a request with a target) and conduct its observations (in multiple filters) within 24h
  2. reduce the photometric data and submit to the CPCS within 24h from the observation (*)
  3. flux calibrations better than 10% (0.1 mag)
  4. perform at least 5 (TBC) tests before December 2013.

(*) Note: the CPCS was created in order to facilitate the homogenous calibration of the photometric reductions. You are welcome to provide your own calibrated data and omit the CPCS step, but we will still need to obtain the data within 24h from the observation.
