Notes. Column densities and excitation temperatures of the different species analysed. In the first block, for the two excitation temperatures, are shown the column densities for species where only one or two rotational transitions were detected in L183, while the L1544 data were derived analysing the ASAI molecular survey. In the second block, the same conditions for L183 as the previous block, but here the L1544 data are from literature. In the last section of the table, the excitation temperatures and column densities for L183 were obtained through a MCMC analysis (see text) and data for L1544 are from literature. ^(*) The column density value for L1544 was obtained scaling that of C¹⁷O reported in Caselli et al. (1999). ^(**)Derived with CLASS HFS routine (see text). ^(***)Derived with non-LTE analysis (see text). Values for L1544 are from Bizzocchi et al. (2014).
