Notes.
In cm-2 assuming Tex = 170 K. The typical error is a combination of the assumption of the excitation temperature and the flux calibration uncertainty (~20%). The determined column density varies with Tex in the interval 100–200 K differently for each molecule, see Fig. 8 and the discussion in Sect. 4.5.3.
