Fig. A.5


c-C3H2 212 → 101 channel maps. For the units of velocity, ordinate, and the wedge as well as for the position of the crosses, see Fig. A.1. The value 0.02 Jy corresponds to ≈0.85 K. The beam size is shown in the lower right corner of the figure. The emission seen at an apparent c-C3 H2 velocity of ≈300 km s−1 is caused by the redshifted part of the CH3C2H J = 50 → 40 line, emitting near 710 km s−1 (see also Figs. 6 and A.6).
