Radio Ammonia Mid-Plane Survey (RAMPS)
The Radio Ammonia Mid-Plane Survey (RAMPS) has surveyed 24 square degrees of the Galactic plane using the Green Bank Telescope (GBT).
RAMPS covers the longitude range l = (10º,40º) and latitude range |b| < 0.4º. The key spectral targets of RAMPS were the ammonia transitions NH3(1,1) to NH3(5,5). Other emission lines in the RAMPS band include transitions of HC5N, HC7N, CH3OH, HNCO, H2O and CCS.
The intrinsic angular resolution of the RAMPS NH3(1,1) data is ~32 arcseconds, and the velocity resolution is 0.2 km/s. The typical rms sensitivity per 0.2 km/s channel of the RAMPS NH3 data cubes is σ(T) ~ 0.16K. Units of the maps are K.km/s.
CADE currently delivers NH3(1,1) to NH3(3,3) integrated intensity and the H2O 6(1,6)–5(2,3) maser line at 22.235 GHz of the pilot RAMPS region using the survey's public data release. Healpix maps made by D. Paradis.
