Abstract:
We present observations of 77 early-type galaxies imaged with the PC1
CCD of the Hubble Space Telescope (HST) WFPC2. "Nuker-law" parametric
fits to the surface brightness profiles are used to classify the
central structure into "core" or "power-law" forms.
Description:
All galaxies were imaged with the high-resolution PC1 CCD in WFPC2 (55
of these were obtained under programs GO 5512, 6099, 6587, and 9107,
which were carried out by our collaboration); the image scale is
0.0456"/pixel. Nearly all galaxies were imaged in the F555W filter
(equivalent to broadband V); images were also obtained in the F814W
filter (broadband I) to provide color information for many galaxies.
