Abstract:
In this paper we describe the first data release of the UltraVISTA
near-infrared imaging survey of the COSMOS field. We summarise the key
goals and design of the survey and provide a detailed description of
our data reduction techniques. We provide stacked, sky-subtracted
images in Y JHKs and narrow-band filters constructed from data
collected during the first year of UltraVISTA observations.
Description:
Matched source catalogue prepared for the first UltraVISTA (DR1
catalogue release. To 5σ limit, our Ks -selected catalogue
contains 216268 sources observed in Y, J, H and Ks bands over the
full UltraVISTA deep area (∼1.3deg2), with NB118 observation over
the "ultra-deep stripes" area.

Note (1): based on COSMOS astrometric reference frame.
Note (2): This bad region flag only indicates objects (with a flag value of T)
at the edge of the Ks detection image; bright stars are not flagged in this
catalogue version.
Note (3): All magnitudes are in AB system, in the VISTA instrumental
magnitude system.
Note (4): for each band, the SExtrator flag is reported indicating if an object
is blended or has otherwise corrupter photometric measurements.
To select objects with non-corrupted photometry for the NB118 data, one
should select in addition only objects with NB118flag<1.
The best possible object sample are those objects which have all flags
equal to zero in all bands.
