Stellar rotation velocities and velocity dispersions along the major
axis of M32, inferred from: the HST data presented in [R19] (resolution 0.1 arcsec);
the ground-based CFHT data obtained by Bender et al. (1996)
(resolution 0.5 arcsec); and the ground-based WHT data presented in [R6] (resolution 0.8 arcsec). Data
points are plotted equidistantly along the abscissa; corresponding
major axis distances are given in the bottom panel. The curves are
predictions of fully general axisymmetric models [R16]. The overall best fit
(solid curve) has a 3.4 million solar mass black hole. Models without
a black hole (dotted curve) cannot reproduce the central peak in the
