HC3N(10 − 9) 0.17 ± 0.04 0.17 ± 0.04 0.31 ± 0.08 1.0 ± 0.3
HCN(3 − 2) 1.00 ± 0.06 1.13 ± 0.06 10 ± 5
HCO+(3 − 2) 0.88 ± 0.05 1.00 ± 0.06 9 ± 4
HOC+(3 − 2)a 0.10 ± 0.05 0.11 ± 0.06 1.0 ± 0.7

Notes. Due to differences in the observed areas, we do not list the ratios between the 3 mm and 1 mm lines (see Sect. 4.5).

(a)

For HOC+(3 − 2), we used the temperature measured in the pixel where it peaks (see Sect. 3.2.1).
