Abstract:
We present a re-reduction and expansion of the Bolocam Galactic Plane
Survey (BGPS), first presented by Aguirre+ (2011ApJS..192....4A 2011ApJS..192....4A) and
Rosolowsky+ (2011, J/ApJS/188/123). The BGPS is a 1.1mm survey of dust
emission in the Northern galactic plane, covering longitudes
-10°<ℓ<90° and latitudes |b|<0.5° with a typical
1σ rms sensitivity of 30-100mJy in a ∼33" beam. Version 2 of the
survey includes an additional ∼20deg2 of coverage in the third and
fourth quadrants and ∼2deg2 in the first quadrant. The new data
release has improved angular recovery, with complete recovery out to
∼80" and partial recovery to ∼300", and reduced negative bowls around
bright sources resulting from the atmospheric subtraction process. We
resolve the factor of 1.5 flux calibration offset between the v1.0
data release and other data sets and determine that there is no offset
between v2.0 and other data sets. The v2.0 pointing accuracy is tested
against other surveys and is demonstrated to be accurate and an
improvement over v1.0. We present simulations and tests of the
pipeline and its properties, including measurements of the pipeline's
angular transfer function. The Bolocat cataloging tool was used to
extract a new catalog, which includes 8594 sources, with 591 in the
expanded regions. We have demonstrated that the Bolocat 40" and 80"
apertures are accurate even in the presence of strong extended
background emission. The number of sources is lower than in v1.0, but
the amount of flux and area included in identified sources is larger.
Description:
The BGPS is described in full detail in Paper I (Aguirre+
2011ApJS..192....4A 2011ApJS..192....4A). The survey uses the 144-element Bolocam array on
the Caltech Submillimeter Observatory, which observes in a band
centered at 268GHz (1.1mm) and a width of 46GHz.
Thirteen nights of additional data were acquired from 2009 December 15
to 2010 January 1.
The sources were extracted using Bolocat with parameters set in the
same way as for the v1 catalog (Rosolowsky+ 2011, J/ApJS/188/123).
There are many sources in v1 that are not in v2 and vice-versa. These
discrepancies occur primarily for faint sources with low
signal-to-noise. Objects in both catalogs are likely to be real since
catalog parameters were selected to minimize false positives. Changing
the quality of the images and the structure of the noise highlights
some new objects and obscures others. The v2 catalog has about a 75%
overlap with the v1 catalog.
