Fig. 4
Panel a: number of velocity components found with ortho c-C3H2 in the selected field as a function of centroid velocity. The bin width is one channel, 1.74 km s−1. Panel b: distribution of linewidths. Panel c: distribution of ortho c-C3H2 column densities. The velocity ranges are colour coded in the background of every panel (see Table 1 for references).
