The Bolocam Galactic Plane Survey (BGPS) is a 1.1 mm continuum survey of the
Galactic Plane made using Bolocam on the Caltech Submillimeter Observatory.
Millimeter-wavelength thermal dust emission reveals the repositories of the
densest molecular gas, ranging in scale from cores to whole clouds. By
pinpointing these regions, the connection of this gas to nascent and ongoing
star formation may be explored. The BGPS coverage totals 192 square degrees
(with 33" FWHM effective resolution). The survey is contiguous over the range
-10.5 ≤ l ≤ 90.5, |b| ≤ 0.5. Towards the Cygnus X spiral arm, the
coverage was flared to |b| ≤ 1.5 for 75.5 ≤ l ≤ 87.5. In addition,
cross-cuts to |b| ≤ 1.5 were made at l = 3, 15, 30 and 31. The total area of
this section is 133 square degrees. With the exception of the increase in
latitude, no pre-selection criteria were applied to the coverage in this region.
In addition to the contiguous region, four targeted regions in the outer Galaxy
were observed: IC 1396 (9 square degrees, 97.5 ≤ l ≤ 100.5, 2.25 ≤ l
≤ 5.25), a region towards the Perseus Arm (4 square degrees centered on l =
111, b=0 near NGC 7538), W3/4/5 (18 square degrees, 132.5 ≤ l ≤ 138.5) and
Gem OB1 (6 square degrees, 187.5 ≤ l ≤ 193.5). The survey has detected
approximately 8,600 sources, to an rms noise level in the maps ranging from 30
to 60 mJy beam-1. The BGPS survey and catalog provide an important
database for sub/millimeter observations with the Herschel Space Observatory,
ALMA, SCUBA-2, APEX, and others.
