Abstract:
We present the Advanced Camera for Surveys General Catalog (ACS-GC), a
photometric and morphological database using publicly available data
obtained with the Advanced Camera for Surveys (ACS) instrument on the
Hubble Space Telescope. The goal of the ACS-GC database is to provide
a large statistical sample of galaxies with reliable structural and
distance measurements to probe the evolution of galaxies over a wide
range of look-back times. The ACS-GC includes approximately 470000
astronomical sources (stars + galaxies) derived from the AEGIS,
COSMOS, GEMS, and GOODS surveys. Galapagos code (Hausler et al.
2011ASPC..442..155H 2011ASPC..442..155H) was used to construct photometric (SExtractor)
and morphological (Galfit) catalogs. The analysis assumes a single
Sersic model for each object to derive quantitative structural
parameters. We include publicly available redshifts from the DEEP2,
COMBO-17, TKRS, PEARS, ACES, CFHTLS, and zCOSMOS surveys to supply
redshifts (spectroscopic and photometric) for a considerable fraction
(∼74%) of the imaging sample. The ACS-GC includes color postage
stamps, Galfit residual images, and photometry, structural parameters,
and redshifts combined into a single catalog.

------------------------------------------------------------------------------
Note (2): the error is 1σ for EGS (Extended Groth Strip) and
3σ for COSMOS
Note (3): Quality of redshift as in VVDS-DEEP (III/250) or DEEP2 (III/268)
The last (rightmost) digit characterises the quality of the redshift:
-2 = Object was effectively unobserved
-1 = Object is identified as a star (i.e., z∼0)
0 = No redshift could be assigned to the 1D spectrum.
1 = 50% confidence in the redshift.
2 = 75% confidence in the redshift.
3 = 95% confidence.
4 = 100% confidence.
9 = Single isolated emission line spectra
A value less than 10 indicates the quality of primary targets, i.e.
objects which have been targeted in the VIMOS spectral slit.
To this quality value, the following number may be added:
+10 = a primary QSO target
+20 = a secondary identified target, i.e. an object which is present
by chance in the spectral slit in addition of the primary target;
thus the secondary object is not ensured to be fully centered
within the slit.
+210 = secondary QSO identified target
