Abstract:
The Fornax Cluster is a conspicuous cluster of galaxies in the
southern hemisphere and the second largest collection of early-type
galaxies within 20Mpc after the Virgo Cluster. In this paper, we
present a brief introduction to the ACS Fornax Cluster Survey -
a program to image, in the F475W (g475) and F850LP (z850)
bandpasses, 43 early-type galaxies in Fornax using the Advanced Camera
for Surveys (ACS) on the Hubble Space Telescope. Combined with a
companion survey of Virgo, the ACS Virgo Cluster Survey, this
represents the most comprehensive imaging survey to date of early-type
galaxies in cluster environments in terms of depth, spatial
resolution, sample size, and homogeneity. We describe the selection of
the program galaxies, their basic properties, and the main science
objectives of the survey, which include the measurement of
luminosities, colors, and structural parameters for globular clusters
associated with these galaxies, an analysis of their isophotal
properties and surface brightness profiles, and an accurate
calibration of the surface brightness fluctuation distance indicator.
Finally, we discuss the data reduction procedures adopted for the
survey.
Description:
Observations for each of the 43 program galaxies were carried out as
part of GO program 10217 between 2004 September and 2005 March. Each
galaxy was imaged within a single orbit, using the ACS Wide Field
Channel (WFC) mode.
