VizieR Online Data Catalog: Radio Ammonia Mid-plane Survey (RAMPS) pilot survey (Hogge+, 2018)
Abstract
The Radio Ammonia Mid-Plane Survey (RAMPS) is a new Galactic midplane molecular line survey, which employs the K-band Focal Plane Array on the Green Bank Telescope (GBT) to image several NH3 inversion lines and the 22.235GHz H2O line.
RAMPS observes 13 molecular transitions: -------------------------------------------------------------------- Mol Transition Frequency Eupper/k Number of (MHz) (K) receivers -------------------------------------------------------------------- NH3 (J,K) = (1,1) 23694.47 23 7 NH3 (J,K) = (2,2) 23722.60 64 7 NH3 (J,K) = (3,3) 23870.08 124 7 NH3 (J,K) = (4,4) 24139.35 201 7 NH3 (J,K) = (5,5) 24532.92 295 7 CH3OH JKp = 101-92A- 23444.78 143 7 HC5N J = 9-8 23963.90 6 7 HC5N J = 8-7 21301.26 5 1 HC7N J = 19-18 21431.93 10 1 CH3OH JKp = 122-111A- 21550.34 479 1 HNCO JKp,Ko = 10,1-00,0 21981.57 1 1 H2O JKp,Ko = 61,6-52,3 22235.08 644 1 CCS J = 2-1 22344.03 2 1 -------------------------------------------------------------------- Note. The quantum numbers given in the "Transition" column are J, the rotational quantum number; K, the projection of J along the molecular axis of symmetry; Kp, the value of K in the limiting case of a prolate spheroid molecule; and Ko, the value of K in the limiting case of an oblate spheroid molecule. CH3OH 122-111A- is a rotational transition within the first vibrationally excited state, i.e., v=1. -------------------------------------------------------------------- We performed observations for RAMPS using the 100m diameter Robert C. Byrd GBT at the NRAO which operates in a nearly continuous frequency range of 0.29-115GHz. In 2014, RAMPS was awarded 210hr of observing time on the GBT for a pilot survey. We performed observations for the RAMPS pilot study between 2014 March 16 and 2015 January 22. (1 data file).- Publication:
