Notes. (a)The S/Ns are calculated from the integrated intensity of the lines inferred from the LTE fits of MADCUBA-SLIM. They are not calculated from the Gaussian fits of individual lines. (b)The error in the integrated intensity is calculated as 
, with δv the velocity resolution of the spectra and Δv the FWHM of the line emission of 20kms−1. (c)The line corresponds to a blend of four individual Ga-n-C3H7OH transitions. The total integrated intensity and the S/N are calculated from the sum of the areas of the individual transitions. (d)Transitions detected at the ≥3 rms noise level in peak intensity. (e)This S/N should be taken with caution since the LTE fit carried out by MADCUBA-SLIM overpredicts the integrated intensity of the line. (*)Transitions that provide the identification of the species with S/N ≥ 6 in integrated intensity.
