VizieR Online Data Catalog: H2O Southern Galactic Plane Survey (HOPS) (Walsh+,
Abstract
We present first results of the H2O Southern Galactic Plane (HOPS), using the Mopra Radio Telescope with a broad-band backend and a beam size of about 2arcmin. We have observed 100deg2 of the southern Galactic plane at 12mm (19.5-27.5GHz), including spectral line emission from H2O masers, multiple metastable transitions of ammonia, cyanoacetylene, methanol and radio recombination lines. In this paper, we report on the characteristics of the survey and H2O maser emission. We find 540 H2O masers, of which 334 are new detections.
