Appendix A: Online Material

In this appendix we present additional material, which may be useful. In particular, we show the list of all the sources in the sampled field, from the SIMBAD Astronomical Database (Table A.1); the integrated intensity map of the C¹⁸O(1-0) emission from our FCRAO observations (Fig. A.1); the channel map of our FCRAO ¹³CO(1-0) data (Fig. A.2); and finally the overlay between the ¹³CO(1-0) clumps and the APEX continuum clumps with the Spitzer emission at 3.6, 8 and 24 $\mu$ m (Fig. A.3).

Table A.1: List of the sources in the sampled field, from the SIMBAD Astronomical Database. Columns (1)-(2): coordinates (J2000.0); Col. (3): distance from the peak emission of the associated clump (see Sect. 4.1); Col. (4): References.

$\begin{figure} \par\includegraphics[angle=-90,scale=0.6]{14177fg12.eps} \end{figure}$	Figure A.1: FCRAO intensity map of the C¹⁸O(1-0) emission, integrated between 25 and 57 km s^-1. The contour levels are from 10 $\sigma$ in steps of 5 $\sigma$ ( $\sigma = 0.3$ K km s^-1). Symbols are as in Fig. 1 (see Table A.1).

Figure A.2:

Channel map of the BU-FCRAO GRS ¹³CO(1-0) data in grey scale and our FCRAO ¹³CO(1-0) emission in black contours. Center velocities of the channels are indicated in the bottom left corner of each panel and increase in steps of 2 km s^-1. Contour levels are drawn from 10 $\sigma$ ( $\sigma = 0.2$ K) in steps of 5 $\sigma$ . The black numbered crosses indicate the peak positions (in the channel corresponding to the peak velocity) of the emission of the 19 molecular clumps identified in the FCRAO ¹³CO(1-0) emission.

Figure A.3:

Composite image of the 24 $\mu$ m (red), the 8 $\mu$ m (green) and 3.6 $\mu$ m (blue) emissions from Spitzer, covering several regions of the large-scale map, corresponding to the single clumps associated with the APEX continuum emission at 870 $\mu$ m. The green contours are the ¹³CO(1-0) emission of the single clumps, integrated over the velocity range of every clump (see Col. 4 of Table 3), and the white contours are the APEX continuum emission at 870 $\mu$ m (from 5 $\sigma$ in steps of 5 $\sigma$ , where $\sigma = 40$ mJy beam^-1). The ¹³CO clumps and the correspondent continuum sources are labelled in the single diagrams. Note that some of the panels are similar because for each clump we integrated on the velocity channels of emission of the clump (see Col. 4 of Table 3).
