Left: GRAVSPHERE2 recovery of the logarithmic density slope profile for the simulated Fornax-like dwarf. The bands denote the 95% CL regions for different numbers of stellar tracers (100, 1000, and 34 518, same as in Fig. 5) including only LOS velocities, as marked. The red, solid line corresponds to the slope from the smoothened density profile from the simulation. Right: same as the left panel but including both LOS and PM velocities.
