Caption: Figure 2.

Line-of-sight velocity distribution of M32 derived from the Gemini/NIFS data at the CO band head (2.3 μm). The radial velocity is shown in the top left panel after removal of the systemic velocity of −200 km s −1. The bottom left panel shows the dispersion, the top right the skewness or h3 component, and the bottom right the kurtosis or h4 component of the LOSVD. These data are the highest S/N data available for the M32 nucleus that resolve the BH sphere of influence.
