Scientific paper

Maps of the J = 1 - 0 13CO and J = 1 - 0, J = 3 - 2 HCO+ emission from GGD 12-15 together with selected spectra are presented. The authors derive a peak column density from the 13CO observations of (NL)H2 ≥ 5×1022cm-2 and a total cloud mass of ≈1×103M_sun;, comparable with the virial mass of the cloud. The maps of integrated J = 1-0 13CO and HCO+ emission show a distribution which is roughly similar to that of total ammonia column density deduced by Güsten and Marcaide, but not to their map of integrated ammonia emission.
