Abstract:
We present a 0.72deg2 contiguous 1.1-mm survey in the central area of
the Cosmological Evolution Survey field carried out to a
1σ∼1.26mJy/beam depth with the AzTEC camera mounted on the 10-m
Atacama Submillimeter Telescope Experiment. We have uncovered 189
candidate sources at a signal-to-noise ratio (S/N)≥3.5, out of
which 129, with S/N≥4, can be considered to have little chance of
being spurious (≲2 per cent). We present the number counts derived
with this survey, which show a significant excess of sources when
compared to the number counts derived from the ∼0.5deg2 area
sampled at similar depths in the Submillimetre Common-User Bolometer
Array (SCUBA) HAlf Degree Extragalactic Survey (SHADES).
Description:
We imaged a 2800 arcmin2 field centred at right ascension
RA(J2000.0)=10:00:30.00 and declination DE(J2000.0)=2:14.00 with AzTEC
mounted on the 10-m ASTE, located at 4800m in the Atacama Desert of
Chile. The survey was carried out from 2008 October 20 to November 30.

Note (1): Notes, including names for the source in other (sub)mm catalogues,
where AzTEC_J refers to the AzTEC/JCMT catalogue (Scott et al. 2008,
Cat. J/MNRAS/385/2225), AzTEC denotes interferometric SMA detections
at 890um (Younger et al. 2007ApJ...671.1531Y 2007ApJ...671.1531Y, 2009ApJ...704..803Y 2009ApJ...704..803Y),
MMJ denotes detections at 1.2mm by the COSBO survey performed with MAMBO
(Bertoldi et al. 2007ApJS..172..132B 2007ApJS..172..132B) and B indicates detection at 1.1mm
by the Bolocam survey carried out at the Caltech Submillimeter Observatory
