Abstract:
We present a UV to mid-infrared multi-wavelength catalog in the
CANDELS/GOODS-S field, combining the newly obtained CANDELS HST/WFC3
F105W, F125W, and F160W data with existing public data. The catalog is
based on source detection in the WFC3 F160W band. The F160W mosaic
includes the data from CANDELS deep and wide observations as well as
previous ERS and HUDF09 programs. The mosaic reaches a 5σ
limiting depth (within an aperture of radius 0.17") of 27.4, 28.2, and
29.7 AB for CANDELS wide, deep, and HUDF regions, respectively. The
catalog contains 34930 sources with the representative 50%
completeness reaching 25.9, 26.6, and 28.1 AB in the F160W band for
the three regions. In addition to WFC3 bands, the catalog also
includes data from UV (U band from both CTIO/MOSAIC and VLT/VIMOS),
optical (HST/ACS F435W, F606W, F775W, F814W, and F850LP), and infrared
(HST/WFC3 F098M, VLT/ISAAC Ks, VLT/HAWK-I Ks, and Spitzer/IRAC 3.6,
4.5, 5.8, 8.0µm) observations. The catalog is validated via stellar
colors, comparison with other published catalogs, zero-point offsets
determined from the best-fit templates of the spectral energy
distribution of spectroscopically observed objects, and the accuracy
of photometric redshifts. The catalog is able to detect unreddened
star-forming (passive) galaxies with stellar mass of 1010M☉ at
a 50% completeness level to z∼3.4 (2.8), 4.6 (3.2), and 7.0 (4.2) in
the three regions. As an example of application, the catalog is used
to select both star-forming and passive galaxies at z∼2-4 via the
Balmer break. It is also used to study the color-magnitude diagram of
galaxies at 0<z<4.
Description:
The Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey
(CANDELS; Grogin et al. 2011ApJS..197...35G 2011ApJS..197...35G; Koekemoer et al.
2011ApJS..197...36K 2011ApJS..197...36K) is designed to document galaxy formation and
evolution over the redshift range of z=1.5-8. The core of CANDELS is
to use the revolutionary near-infrared HST/WFC3 camera, installed on
HST in 2009 May, to obtain deep imaging of faint and faraway objects.
The GOODS-S field, centered at RAJ2000=03:32:30 and DEJ2000=-27:48:20
and located within the Chandra Deep Field South (CDFS; Giacconi et al.
2002, Cat. J/ApJS/139/369), is a sky region of about 170arcmin2
which has been targeted for some of the deepest observations ever
taken by NASA's Great Observatories, HST, Spitzer, and Chandra as well
as by other world-class telescopes. The field has been (among others)
imaged in the optical wavelength with HST/ACS in F435W, F606W, F775W,
and F850LP bands as part of the HST Treasury Program: the Great
Observatories Origins Deep Survey (GOODS; Giavalisco et al. 2004, Cat.
II/261); in the mid-IR (3.6-24um) wavelength with Spitzer as part of
the GOODS Spitzer Legacy Program (PI: M. Dickinson).
The CDF-S/GOODS field was observed by the MOSAIC II imager on the CTIO
4m Blanco telescope to obtain deep U-band observations in 2001
September. Another U-band survey in GOODS-S was carried out using the
VIMOS instrument mounted at the Melipal Unit Telescope of the VLT at
ESO's Cerro Paranal Observatory, Chile. This large program of ESO
(168.A-0485; PI: C. Cesarsky) was obtained in service mode
observations in UT3 between 2004 August and fall 2006.
In the ground-based NIR, imaging observations of the CDFS were carried
out in J, H, Ks bands using the ISAAC instrument mounted at the Antu
Unit Telescope of the VLT. Data were obtained as part of the ESO Large
Programme 168.A-0485 (PI: C. Cesarsky) as well as ESO Programmes
64.O-0643, 66.A-0572, and 68.A-0544 (PI: E. Giallongo) with a total
allocation time of ∼500 hr from 1999 October to 2007 January. The
CANDELS/GOODS-S field was also observed in the NIR as part of the
ongoing HAWK-I UDS and GOODS-S survey (HUGS; VLT large program ID
186.A-0898; PI: A. Fontana; A. Fontana et al., in preparation) using
the High Acuity Wide field K-band Imager (HAWK-I) on VLT.

--------------------------------------------------------------------------------
Note (1): The limiting magnitude here is derived as
mlim=-2.5log10(A<σ2>)0.5+zp,
where <σ2> is the average of the squared rms in the SExtractor
F160W segmentation map of each source, A is the area of 1 arcsec2, and
zp is the zero point of F160W.
Note (2): Flag as follows:
0 = non-contaminated sources
1 = sources detected on star spikes, halos; and the bright stars that produce
those spikes and halos
2 = sources detected by SExtractor at the image edges or on the few artifacts
of the F160W image
3 = sources with both the flag of "1" and "2".
Note (3): In HST bands, the weight is the exposure time of the source,
while in other bands, it is a relative weight.
Note (4): For sources whose isophotal radius smaller than 2.08 pixels,
these parameters are replaced by FLUX_APER and FLUXERR_APER measured
within a radius of 0.125" (2.08 pixels). See Section 3.2 for details.
