Fig. 3
Spectra of the CH3CN and CH313CN transitions that are not significantly affected by blending with other lines. The vertical dashed line denotes the systemic velocity (–3.9 km s-1), while the dotted lines mark the beginning of the line wings. The arrow in the panel of the K = 8 line marks the frequency of the CH2OHCHO(202,18–193,17) transition detected by Beltrán et al. (2009).
