The CO Heterodyne Inner Milky Way Plane Survey (CHIMPS) mapped the 13CO(3-2) and C18O(3-2) emission in the inner Galactic plane with the James Clerk Maxwell Telescope (JCMT).

CHIMPS mapped the longitude range l = (28°,46°) and latitude range |b| ≤ 0.5°, across the radial velocity range VLSR = (-75, +150) km/s. The 12CO(3-2) emission across the same region was mapped by the COHRS survey.

The original angular resolution of CHIMPS is 15 arcseconds and the velocity resolution is 0.5 km/s. The typical rms sensitivity per channel of the CHIMPS data cubes is σ(T) ~ 0.5K .

CADE currently delivers 13CO(3-2) and C18O(3-2) integrated intensity and peak brightness maps of the full CHIMPS region using the survey's public data release.
