Abstract:
We study the internal color properties of a morphologically selected
sample of spheroidal galaxies taken from the Hubble Space Telescope
(HST) Advanced Camera for Surveys (ACS) Early Release Observation
program of UGC 10214 ("the Tadpole"). By taking advantage of the
unprecedented high resolution of the ACS in this very deep data set,
we are able to characterize spheroids at subarcsecond scales. Using
the V606 and I814 bands, we construct V-I color maps and extract
color gradients for a sample of spheroids at I814<24mag.
Description:
The spheroids in our study were selected from one of the first science
observations acquired by the ACS Wide Field Channel (WFC) as part of
the Early Release Observations (EROs) program.

Note (1): The asymmetry (A) is defined in Abraham at al.
(1996MNRAS.279L..47A 1996MNRAS.279L..47A): "A was measured by rotating and
self-subtracting the galaxy image from itself"; asymetric
or disturbed galaxies have a high A.
Note (2): The central concentration (C) is defined in Abraham at al.
(1996MNRAS.279L..47A 1996MNRAS.279L..47A): "C was determined from measurements of the
intensity-weighted second-order moments of the galaxy images";
early-type galaxis have high C.
