Observations for the Bolocam Galactic Plane Survey (BGPS) took place from June 2005 until September 2007 and covers 170 square degrees of the galactic plane visible from the

northern hemisphere The Northern Hemisphere is the half of Earth that is north of the Equator. For other planets in the Solar System, north is defined as being in the same celestial hemisphere relative to the invariable plane of the solar system as Earth's Nort ...

. The survey detected 8400 sources to a limiting non-uniform 1-sigma noise level in the range 30 to 60 mJy/beam. This survey is the first large-area, systematic and uniform survey of the galactic plane in the millimeter continuum. Additional data was acquired in 2009 and released in 2013. All data are currently available fro
IPAC

Survey coverage

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: IC1396 (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 NGC7538), W3/4/5 (18 square degrees, 132.5 ≤ l ≤ 138.5) and Gem OB1 (6 square degrees, 187.5 ≤ l ≤ 193.5).
