Radial profiles of the second moments of the velocity for the six Aurigaia mocks from Grand et al. (2018). The top row has results for Au6, Au16, and Au21, the bottom row shows Au23, Au24, and Au27. Scattered points with error bars show the results for the mock samples described in Table 3 while solid lines show the result for the stellar particles in the final simulation snapshot of the simulated galaxies. The dashed lines in the left column show the exponential fit to the profile of the mock sample, while the dotted lines show the fit to the profile of the simulation particle sample.
