Velocity dispersion cumulative distribution. Red curve shows the cumulative distribution for all points with good velocity
dispersion measurements, while the black curve uses only points close to the central core. The sharp transition in velocity
dispersion produces a change in the cumulative distribution's slope, which can be observed both locally (central region) and
globally (entire map). The inset shows the spatial distribution of the points used, and velocity dispersion contours are overlaid
in gray.
