Fig. 2.

Map of the H2 column density derived from far-infrared images taken by Herschel (Spezzano et al. 2016). The dashed squares cover 40″ in the x- and y- direction and indicate the regions where the molecules c-C3H2 and CH3OH peak. The white circle represents the beam of the Herschel/SPIRE instrument. On the left part of the figure we show the resulting spectra of the JKa, Kc = 40,4 – 30,3 transition of HCCO averaged over the dashed squares. The red line plots the CLASS Gaussian fit.
