The Radio Ammonia Mid-plane Survey (RAMPS) pilot survey

The Radio Ammonia Mid-Plane Survey (RAMPS) is a molecular line survey that aims to map a portion of the Galactic midplane in the first quadrant of the Galaxy (l = 10°–40°,|b|≼0°.04) using the Green Bank Telescope. We present results from the pilot survey, which has mapped approximately 6.5 square degrees in fields centered at l = 10°, 23°, 24°, 28°, 29°, 30°, 31°, 38°, 45°, and 47°. RAMPS observes the NH₃ inversion transitions NH₃(1,1)–(5,5), the H₂O 6_1,6–5_2,3 maser line at 22.235 GHz, and several other molecular lines. We present a representative portion of the data from the pilot survey, including NH₃(1,1) and NH₃(2,2) integrated intensity maps, H₂O maser positions, maps of NH₃ velocity, NH₃ line width, total NH₃ column density, and NH₃ rotational temperature. These data and the data cubes from which they were produced are publicly available on the RAMPS website (http://sites.bu.edu/ramps/).
