Top panel: velocity dispersion, σμ, as a function of the mF814W magnitude for MS, SGB, and RGB stars (black circles) and for white dwarfs (blue circles). Bottom panel. σμ against the logarithm of stellar mass for MS, SGB, and RGB stars. We used light-red colors to represent the best-fit straight line. The horizontal segments indicate the magnitude and mass interval associated with each point.
