COHRS
The CO(3-2) High-resolution Survey of the Galactic Plane mapped the 12CO(3-2) emission in the inner Galactic plane using the HARPS instrument on the James Clerk Maxwell Telescope (JCMT).
COHRS covered the longitude range l =(10°,65°) and latitude range |b| < 0.°5. The total survey area is 29 square degrees. The 13CO(3-2) and C18O(3-2) emission across a significant fraction of the COHRS area has been mapped by CHIMPS.
The original angular resolution of COHRS is 16 arcseconds and the velocity resolution is 1 km/s. The typical rms sensitivity per channel of the COHRS data cubes is σ(T) ~ 1K .
CADE currently delivers 12CO(3-2) integrated intensity and peak brightness maps of the full COHRS region using the survey's public DR1. To facilitate processing, the input WCS FITS data cubes were convolved to 33 arcseconds prior to the generation of the HEALpix moment maps delivered by CADE.
