Abstract:
We present results from a survey carried out by the Balloon-borne
Large Aperture Submillimeter Telescope (BLAST) on a 9deg2 field near
the South Ecliptic Pole at 250, 350, and 500um. The median 1σ
depths of the maps are 36.0, 26.4, and 18.4mJy, respectively. We apply
a statistical method to estimate submillimeter galaxy number counts
and find that they are in agreement with other measurements made with
the same instrument and with the more recent results from
Herschel/SPIRE. Thanks to the large field observed, the new
measurements give additional constraints on the bright end of the
counts. We identify 132, 89, and 61 sources with S/N≥4 at 250, 350,
500um, respectively and provide a multi-wavelength combined catalog of
232 sources with a significance ≥4σ in at least one BLAST band.
Description:
During the BLAST 2006 Antarctic flight, deep observations (68hr) were
carried out over a 9deg2 field centered on (70:94-53:50) near the
South Ecliptic Pole (SEP).

Global Notes:
Note (G1): Flux densities are not corrected for Eddington-type bias.
Values of flux density and uncertainty for source 1 come from
aperture photometry. See Section 4.3 for details.
