Notes. Upper limits have been derived for positions that do not show significant emission. Values derived from distorted line profiles are written in parenthesis. Uncertainties are estimated to be about 20% from the radiative transfer modeling. The last three rows contain values derived from the column densities of the less abundant isotopologues C17O, H13CN, and H13CO+. Note that the main isotopologues of these species are detected at all considered positions.
