The purpose of these exercises is to simulate finding astrophysical parameters from Gaia data, and addressing scientific problems through this. Our main focus is on using the low resolution BP/RP data for this, but we can include the information from astrometry and possibly also high-resolution RVS data. The exact aim depends on which challenges are suggested and which are popular.
