Fig. 3
As in Fig. 2 but for the C2H N = 4 − 3, J = 7∕2− 5∕2 doublet, both c−C3H2 transitions and SO2 184,14 − 183,15 (
= 11 mJy beam−1 km s−1 and 
= 25 mJy beam−1 km s−1). For SO2, the emission is above 4σ. Black contours in moment 1 maps represent 10, 15 and 20σ for C2 H, 6 and 8σ for c−C3H2, and 5 and 7σ for SO2. Panels g and h represent a zoomed-in region.
