TL;DR
The Bolocam Galactic Plane Survey (BGPS) provides a detailed 1.1 mm continuum map of a large portion of the northern Galactic Plane, detecting thousands of clumps and detailing data reduction and calibration methods.
Contribution
This paper introduces the BGPS survey, its data reduction techniques, and calibration procedures, offering a comprehensive resource for Galactic Plane millimeter-wave observations.
Findings
Detected approximately 8400 clumps in the surveyed area.
Extended emission larger than about 5.9 arcminutes is mostly attenuated.
Identified a possible systematic flux calibration offset.
Abstract
We present the Bolocam Galactic Plane Survey (BGPS), a 1.1 mm continuum survey at 33" effective resolution of 170 square degrees of the Galactic Plane visible from the northern hemisphere. The survey is contiguous over the range -10.5 < l < 90.5, |b| < 0.5 and encompasses 133 square degrees, including some extended regions |b| < 1.5. In addition to the contiguous region, four targeted regions in the outer Galaxy were observed: IC1396, a region towards the Perseus Arm, W3/4/5, and Gem OB1. The BGPS has detected approximately 8400 clumps over the entire area to a limiting non-uniform 1-sigma noise level in the range 11 to 53 mJy/beam in the inner Galaxy. The BGPS source catalog is presented in a companion paper (Rosolowsky et al. 2010). This paper details the survey observations and data reduction methods for the images. We discuss in detail the determination of astrometric and flux…
