Abstract:
We present the multiwavelength ultraviolet to mid-infrared catalog
of the UKIRT Infrared Deep Sky Survey (UKIDSS) Ultra-Deep Survey
field observed as part of the Cosmic Assembly Near-infrared Deep
Extragalactic Legacy Survey (CANDELS). Based on publicly available
data, the catalog includes the CANDELS data from the Hubble Space
Telescope (near-infrared WFC3 F125W and F160W data and visible ACS
F606W and F814W data); u-band data from CFHT/Megacam; B, V, Rc, i',
and z' band data from Subaru/Suprime-Cam; Y and Ks band data from
VLT/HAWK-I; J, H, and K band data from UKIDSS (Data Release 8); and
Spitzer/IRAC data (3.6, 4.5um from SEDS; 5.8 and 8.0um from SpUDS).
The present catalog is F160W-selected and contains 35932 sources over
an area of 201.7arcmin2 and includes radio- and X-ray-detected
sources and spectroscopic redshifts available for 210 sources.
Description:
The present multiwavelength catalog is based on public data in the
CANDELS UDS field (J2000 position: 02:17:37.5-05:12:00) located within
the original UDS field. It includes:
* CANDELS HST/ACS (F606W, F814W) and HST/WFC3 (F125W, F160W);

* CFHT U-band (UKIDSS; Almaini et al. in prep.),
* SUBARU B, V, Rc, i', z' (SXDS; Furusawa et al. 2008, Cat. J/ApJS/176/1)
* VLT/HAWK-I Y and Ks bands (HUGS; Fontana et al. in prep.)
* UKIRT/WFCam J, H, K (UKIDSS DR8; Almaini et al. in prep.)

* Spitzer/IRAC SpUDS 5.8, 8.0um (PI: J. Dunlop).
The catalog is F160W-selected and contains 35932 sources over an area
of 201.7 square arcmin and includes radio and X-ray detected sources
and spectroscopic redshifts available for 210 sources.

Note (1): From the F160W-selected SExtractor catalog.
Note (2): In the F160W image.
Note (3): At the position of the source in the F160W image (see Section 3.3
for details).
Note (4): A specific flag coding is used to designate suspicious sources that
fall in contaminated regions. The values are:
0 = Non-contaminated sources
2 = Sources detected by SExtractor at the image edges or on the few artifacts
of the F160W image. It accounts for 230 sources that are, for a majority
of them, not real but that are kept in the catalog to conserve the
SExtractor original number of sources.
1 = Sources detected on star spikes, halos and the bright stars that produce
those spikes and halos themselves (706 sources). A large fraction of
these sources are real but the photometry of these sources - on which the
Template-fitting photometry software TFIT run is based (see Section 4) -
is contaminated by a neighbor star.
Note (5): We consistently report values of -99 if the source has no data or is
strongly contaminated by a star spike in one specific band.
According to the statistics, photometry software such as SExtractor
and TFIT can eventually provide slightly negative flux densities for
a source. We kept those negative flux densities in the catalog.
Upper limit on the source flux density can eventually be derived
from its flux uncertainty.

Source types for galaxies in the radio source catalog from Simpson et
al. 2006, Cat. J/MNRAS/372/741 and X-ray source catalog from Ueda et
al. 2008, Cat. J/ApJS/179/124 are coded as "RadioS(Si06)" and
"XRay(U08)" respectively (or both for the only source that was
detected in radio and X-ray, namely source #24437). Possible (but
questionable) counterparts of X-ray and radio sources are indicated by
a "?". Two sources falling within 1 arcsec of the two X-ray extended
source candidates (sources #7217 and #9461) are coded as
"extXRay(U08)".
