Abstract:
VIDEO is a ∼12 square degrees survey in the near-infrared Z, Y, J, H
and Ks bands,over the ELAIS-S1, XMMLS, and ECDFS extragalactic fields.
This document describes the catalog released for the deep stracked
data in the VIDEO-XMM3 field, which also covers the
Canada-France-Hawaii Telescope Legacy Survey Deep-1 field (CFHTLS-D1).
Description:
The released VIDEO data reach a 5σ AB-magnitude depth of Z=25.7,
Y=24.5, J=24.4, H=24.1 and Ks=23.8 in 2 arcsec diameter apertures (the
full depth of Y=24.6 will be reached within the full integration time
in future releases). To the 5σ limit, the Ks catalog contains
198718 sources over 1.8 square degrees. The Ks-selected catalog
provides band-merged photometry using the Ks-band as the detection
image and extracting photometry from the shorter wavelength imaging
data. The authors recommend using only those sources with Ks<23.5 for
most studies as this gives a completeness of ∼90 per cent (Jarvis et
al., 2013MNRAS.428.1281J 2013MNRAS.428.1281J). In the Ks-selected band-merged catalog,
columns where the value is "NaN" denote that the object was detected
at the position of the Ks-band source with negative flux, this occurs
over all apertures and filters for different objects, but is mostly a
problem for the larger aperture.
The VIDEO survey was specifically designed to enable the evolution of
galaxies and large structures to be traced as a function of both
epoch and environment from the pre sent day out to z=4, and active
galactic nuclei (AGNs) and the most massive galaxies up to and into
the epoch of reionization. With its depth and area, VIDEO is able to
fully explore the period in the Universe where AGN and starburst
activity were at their peak and the first galaxy clusters were
beginning to virialize. VIDEO therefore offers a unique data set with
which to investigate the interplay between AGN, starbursts and
environment, and the role of feedback at a time when it was
potentially most crucial.

Note (1): Merged class flags as follows:
1 = galaxy
0 = noise
-1 = star
-2 = probable star
-3 = probable galaxy
-9 = saturated
Note (2): The SExtractor flag is provided in the column denoted ERRBITS,
indicating if an object is blended or has otherwise corrupted measurements.
The best possible object sample are those objects which have ERRBITS = 0.
