Excitation temperatures for molecules where a determination was possible. The species are ordered by their binding energies taken from Minissale et al. (2022) and Ligterink & Minissale (2023). The binding energy of the isotopologues was assumed to be the same as the major isotopologue. Band 3 results are shown in blue and Band 7 (PILS) in pink. PILS results with a fixed temperature are not shown. The temperatures for molecules from Jørgensen et al. (2018) are shown with either 300 ± 60 K or 125 ± 25 K depending on the group with which they were associated.
