Maps

RAMPS has completed its pilot survey, having mapped approximately 6.5 degrees² in fields centered at Galactic longitudes l=10˚, 23˚, 24˚, 28˚, 29˚, 30˚, 31˚, 38˚, 45˚, and 47˚. Shown below are maps of the NH₃(1,1) integrated intensity and 1^st moment, NH₃(2,2) integrated intensity, NH₃ rotational temperature, NH₃ column density, NH₃(1,1) main line optical depth, NH₃ line width, velocity, and filling fraction. In order to avoid spurious detections, the integrated intensity and first moment maps were masked such that we only summed over channels with intensities greater than 5σ. We used PySpecKit (Ginsburg & Mirocha 2011), a Python spectral analysis toolkit, to fit the NH₃(1,1) and (2,2) spectra in order to create the maps of the NH₃ rotational temperature, NH₃ column density, NH₃(1,1) main line optical depth, NH₃ line width, velocity, and filling fraction. We only performed this analysis on spectra that had a significant detection of both NH₃(1,1) and (2,2) emission.
