Abstract This proposal has several objectives. First, the imaging data will be used to determine the precise positions of the centers of the galaxies, to see if the central region is bright enough to do long slit spectroscopy with the FOC f/48 spectrograph, and finally to study the radial intensity and color profile in the spectral region between 2200A and 4500A. In addition, f/288 data will be obtained in those few cases where it is warranted by the f/96 exposures. The spectroscopy will be attempted only in the cases where the central region is bright enough to determine a good velocity dispersion. ------------------------------------------------------------------------------------ 8.

Description of proposed observations. ------------------------------------------------------------------------------------ 12. 64% of the observing time for this project is to be charged to P. Crane's guaranteed time. 36% of the observing time for this project is to be charged to I.R. King's guaranteed time. The observing sequences may have to be modified to include neutral density filters depending on the initial exposures. ------------------------------------------------------------------------------------ 13. FOC images at f/96 will be used to a) locate precisely the center of several elliptical galaxies, b) determine if these centers are bright enough for f/48 velocity dispersion measurements c) study the radial profile from 2500A to 4500A and d) perform spectroscopic observations to determine the velocity dispersion in the central region. ------------------------------------------------------------------------------------ 11.
