The purpose of these mocks is to test how well a Jeans analysis, a slope analysis (WP2011), or a combination of both, does at recovering the input parameters used to generate the mocks, specially the axion mass.
All the data files provided consist of 6 columns: x,y,z,vx,vy,vz. Coordinates are given in kpc, and velocities in Km/s.
Each Mock file contains two galaxy-like mocks, Fornax (for) and Sculptor (scl).
The details on all the parameters, as well as on the model, used to produce the mocks can be found in https://arxiv.org/abs/1609.05856. These mocks were used to produce figures 3-6 therein.
