The Nuker team has STIS Ca triplet spectroscopy of the centers of 10 early-type galaxies. We have measured the first four moments of the losvd's from these data using three techniques: FQ, FCQ and Penalized Maximum Likelihood. To complement the modelling of the stellar orbital structure (Gebhardt, this session), we will compare these moments to other properties of the galaxies. These properties include the ground-based kinematics (e.g., global dispersion) and photometric properties (e.g., bulge luminosity). The sample shows a tendancy toward negative H4 values (i.e., boxy losvd's) near the center. The galaxies that are significantly negative are N3608 and N4473, both of which show signs of merger. We acknowledge support from HST grant GO-07388.01 and LTSA grant NAG5-8238 to D. Richstone.
