Abstract:
The Carnegie-Irvine Galaxy Survey (CGS) is a long-term program to
investigate the photometric and spectroscopic properties of a
statistically complete sample of 605 bright (BT<12.9mag), southern
(δ<0°) galaxies using the facilities at Las Campanas
Observatory. This paper, the first in a series, outlines the
scientific motivation of CGS, defines the sample, and describes the
technical aspects of the optical broadband (BVRI) imaging component of
the survey, including details of the observing program, data reduction
procedures, and calibration strategy. The overall quality of the
images is quite high, in terms of resolution (median seeing ∼1"),
field of view (8.9'x8.9'), and depth (median limiting surface
brightness ∼27.5, 26.9, 26.4, and 25.3mag/arcsec2 in the B, V, R,
and I bands, respectively). We prepare a digital image atlas showing
several different renditions of the data, including three-color
composites, star-cleaned images, stacked images to enhance faint
features, structure maps to highlight small-scale features, and color
index maps suitable for studying the spatial variation of stellar
content and dust. In anticipation of upcoming science analyses, we
tabulate an extensive set of global properties for the galaxy sample.
These include optical isophotal and photometric parameters derived
from CGS itself, as well as published information on multiwavelength
(ultraviolet, U-band, near-infrared, far-infrared) photometry,
internal kinematics (central stellar velocity dispersions, disk
rotational velocities), environment (distance to nearest neighbor,
tidal parameter, group, or cluster membership), and HI content.
Description:
All the images for CGS were taken with the du Pont 2.5m telescope,
during the period 2003 February to 2006 June, spread over 69 nights
and nine observing runs. Table 2 gives a log of the observations. Each
galaxy was imaged in the Johnson B and V and Kron-Cousins R and I
filters.
