FUGIN
The FOREST Unbiased Galactic plane Imaging survey with the Nobeyama 45-m telescope (FUGIN) project was one of the legacy projects utilizing the new multi-beam receiver FOREST (FOur-beam REceiver System on the 45 m Telescope).
FUGIN observed the the 12CO(1-0), 13CO(1-0) and C18O(1-0) molecular line transitions across the longitude ranges l = (+10°,+50°) and l = (+198°,+236°), within a latitude range of |b| < 1°. The total survey area is 80 square degrees for 12CO, and 76 square degrees for 13CO and C18O.
The intrinsic angular resolution of the FUGIN survey data is ~20 arcseconds, and the velocity resolution is 1.3 km/s. The typical rms sensitivity per 1.3 km/s channel of the original FUGIN data cubes is σ(T) ~0.6K for 12CO and σ(T) ~0.3K for 13CO and C18O.
CADE currently delivers 12CO(1-0), 13CO(1-0) and C18O(1-0) integrated intensity and peak brightness maps of the full FUGIN region using the survey's public data release. To facilitate processing, the original WCS FITS data cubes were smooth to 33 arcseconds via convolution with a Gaussian kernel prior to the generation of the HEALpix moment maps delivered by CADE.
