Velocity dispersion as a function of stellar mass for 1G (top panels) and 2G (bottom panels) stars. The labels at the bottom of the plots indicate the average radius in units of half-light radius for stars in each field, and the name of the field. The best-fit values of n and μ are indicated at the top right of each panel. Shaded regions represent the 5th to 95th percentile range of the models.
