Abstract:
We introduce the Serendipitous H-ATLAS-fields Observations of Radio
Extragalactic Sources (SHORES) multiple pencil beam survey that
observed at 2.1GHz with the Australia Telescope Compact Array (ATCA)
29 fields in total intensity and polarization within the
Herschel-ATLAS Southern Galactic Field. This paper presents the
observations, calibration and analysis of the 27 shallow fields that
cover an overall area of ∼26 square degree with increasing sensitivity
towards the phase centers of each pointing according to the ATCA 22 m
dish response function, down to σ≲33uJy. Two additional (deep)
fields have been observed to even higher sensitivity. All the SHORES
observations have been calibrated to account also for linear
polarization. Polarization and deeper field analysis will be presented
in future papers. The SHORES shallow-field sample considered in the
present paper counts 2294 sources detected with BLOBCAT to
signal-to-noise ratio SNR≳4.5. Simulations determined that our
procedure and final catalog is 95% reliable above 497.5uJy and 95%
complete to the SNR≳4.5 significance level. By exploiting ATCA E-W
6km configuration we reached resolutions of 3.2"x7.2", to which level
81% of our sources are unresolved. We determined source counts down to
the 150uJy level. For the sources with a counterpart in H-ATLAS, the
FIR-radio correlation is calculated and discussed.
Description:
SHORES survey that observed 29 fields in total intensity and
polarization within the Herschel-ATLAS Southern Galactic Field via the
2GHz Australia Telescope Compact Aarray (ATCA) with a bandwidth
centered at 2.1GHz.
