VizieR Online Data Catalog: MALT90 Catalogue (Rathborne+, 2016)

Using the 22-m Mopra telescope, MALT90 obtained 3-arcminx3-arcmin maps towards 2 014 locations along the Galactic plane. Jackson et al. (2013) provides the full details of the survey strategy, observing procedure, mapping parameters, and data reduction. 1 The map locations were selected to cover clumps identified from the ATLASGAL 870um dust continuum emission survey (Schuller et al. 2009).

The catalogue contains an entry for each of the clumps covered by the MALT90 survey. While the total number of spectra extracted towards the clumps is 3246, in 311 cases there were two distinct velocity components detected along the line of sight. In these cases, we report separate entries ('A' and 'B' components) which leds to a total of 3556 entries in the catalogue.
