Notes. The quoted error is the 3σ (statistical and calibration) error from the fitting. (a)Abundances derived using the H2 column density N(H2) = 1.02 × 1022 cm−2, adopted from Montillaud et al. (2015). The value is the average of the source (reff = 23′′). (b)The temperature was fixed to Tk derived from methanol. (c)32S∕34S = (3.3 ± 0.5) (DGC/kpc) + 4.1 ± 3.1(~32 ± 5 for our cores), adopted from Chin et al. (1996).
