Notes. The coordinates of the center of the emission of each species are derived from the task imfit applied to the mean maps. (a) Quantity kept fixed during the fitting procedure; (b) for CH3COOH Mininni et al. (2020) found that the values of Tex, N, and X were in the range 200–299 K, 4.3–8.4 × 1017 cm−2, and 4.3–8 × 10−8, respectively. The values reported in this table are the mean values of the ranges, while the errors cover the entire ranges.(c) From CH3NCO υb = 1;(d) from 
, where the column density was multiplied by the factor 12C/13C = 37.
