Notes. The velocity integrated intensities computed using the NOEMA data and reported in the 5th column were averaged over the IRAM-30m half-power beam, used in ASAI. The column densities in column six were computed using the ASAI (upper part) and NOEMA (bottom part) data, and considering a beam dilution factor for a source of 20″. We derived those quantities assuming LTE and an excitation temperature of 30 K. The uncertainties associated include the 1σ noise RMS and a 10% error on the flux calibration. Please note that because the flux was integrated over a larger area, the RMS given in this table differs from the value reported in Tab. 2.
