The Mopra Southern Galactic Plane CO Survey - Data Release 1

We present observations of the first 10 degrees of longitude in the Mopra CO survey of the southern Galactic plane, covering Galactic longitude l = 320- 330 degrees and latitude b=+/- 0.5 degrees, and l = 327- 330 degrees, b= +0.5-1.0 degrees. These data have been taken at 35-arcsec spatial resolution and 0.1 km s(-1) spectral resolution, providing an unprecedented view of the molecular clouds and gas of the southern Galactic plane in the 109-115 GHz J = 1-0 transitions of (CO)-C-12, (CO)-C-13, (CO)-O-18, and (CO)-O-17. Together with information about the noise statistics from the Mopra telescope, these data can be retrieved from the Mopra CO website and the CSIRO-ATNF data archive.
