CHIMPS
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. 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.
Please contact us cade@irap.omp.eu if you require CHIMPS maps at a different angular resolution for your science. Data from CHIMPS2 will be incorporated as it becomes publicly available.
