HOPS
The H2O southern Galactic Plane Survey (HOPS) was a survey of selected molecular line transitions in the 12mm window with the Mopra radio-telescope. The HOPS survey covers a longitude range l = (-70°,+30°) and a latitude range of |b| < 0.5°. The total survey area is 100 square degrees.
The key spectral targets of HOPS were H2O masers, the ammonia transitions NH3(1,1), NH3(2,2), NH3(3,3) and NH3(6,6), HC3N (3-2) and the RRL H69α.
The intrinsic angular resolution of the HOPS survey data is ~2 arcminutes, and the velocity resolution is 0.43 km/s. The typical rms sensitivity per 0.43 km/s channel of the HOPS data cubes is σ(T) ~ 0.1K.
CADE currently delivers NH3(1,1), NH3(2,2), NH3(6,6) and HC3N (3-2) integrated intensity and peak brightness maps of the full HOPS region using the survey's public data release.
