 The output formats are:
   * //cart6D//: ''x, y, z, v_x, v_y, v_z'', with positions in kpc and velocities in km/s.
-  * //Gaia/Theia//: ''RA, Dec, PM_RA, err(PM_RA), PM_Dec, err(PM_Dec), v_LOS, err(v_LOS)'', with coordinates in decimal degrees, PMs in mas/yr and LOS velocities in km/s.

 For each physical/astronomical setup, we have files with 1000 or 10000 system velocities (even 100000 system velocities for GCs), plus possible additional field stars. You are encouraged to run your models on the first 5 mocks of 1000 and on the mock of 10000. For the cart6D mocks, we propose to only analyze those using the //z// axis for the LOS.
 ==== Modeling modes ====
-You are encouraged to run your models on these mocks, both in //LOS-only// mode and in //LOS+PM// mode.
+You are encouraged to run your models on these mocks, both in //LOS-only// mode and in //LOS+PM// mode. And to be fair, you should assume radial profiles of stellar density, mass density and stellar velocity anisotropy that are either non-parametric or parametrized with the correct general shape, but with free inner and outer slopes (for densities) or anisotropies, and free scales (for the stellar and mass densities and for the velocity anisotropy).
 ==== Links to new mocks ====
-You can find the mocks [[http://www.iap.fr/users/gam/GC5_SphericalMocks.tar.gz|here]] (290 MB .tar.gz file), as well as [[http://www.iap.fr/users/gam/dSph_cart6d.tar.gz|here]] for the dSph cart6D ones (2.4 MB). The format of the individual files is CSV (easy to read in ''TopCat'') for the former and ASCII for the latter. If you previously worked this summer with ASCII files for GCs found on this site, please start again with the CSV files.
