Appendix B: Spectroscopic parameters, maps, and rotational diagrams

Table B.1

Spectroscopic parameters of the observed transitions.

thumbnail Fig. B.1

Integrated intensity of all the observed c-C3H2 and CCH transitions. The upper state energy level and the principal quantum numbers are shown for each transition. The smaller scale maps have been convolved to the spatial resolution of 15′′to improve the S/N.

Rotational diagrams for CCH (top), c-C3H2 (middle), and C18O (bottom) along the Herschel strip. Data have been convolved to 40′′  for CCH and C18O, and to 29′′  for c-C3H2. Green diamonds represent the MADEX simulation towards the IF (cf. Sect. 4.2).
