Notes. For NGC 4418, the range of values represents the confidence interval of the χ2 minimization in the best fit model. Data for Sgr B2(N), Sgr B2(OH), the Orion Bar, TMC-1, and NGC 253 were taken from Martín et al. (2006). Data for Arp 220, NGC 1068, and PKS 1830-211, were taken from Martín et al. (2011), Aladro et al. (2013), and Muller et al. (2011) respectively.
