Notes. Trot: Rotational temperature. Ncol: Column density. Zrot: Partition function. The resulting fits are plotted in Fig. 4 on top of the data points we used for the fits (extracted from the individual line fits as listed in Table A.1). Species with unreliable fits due to a very low number of data points or extremely high data dispersion in them, are not shown. These species, and others with a very low number of detected lines here, will be revisited in future publications of similar 4.3 to 1.0 mm surveys carried out with the IRAM-30m telescope.
