Fig. 1
Observed spectra of HCNH+ J = 3− 2 obtained with the IRAM 30 m telescope. For each spectrum the velocity interval shown on the x-axis is ± 20 km s−1 around the systemicvelocity listed in Table A.1 of Fontani et al. (2011). The red curves represent Gaussian fits to the detected lines. For 18 089–1752 a two-Gaussian fit was performed.
