Appendix A: Figures, molecular line results, and spectral energy distributions

In Fig. A.1, we present different panels for each observed source (including the spectra at 3 mm), zero-order moment (integrated intensity) maps for different molecular lines, and a comparison between the emission at 8 μm and at submillimeter (500 μm or 850 μm) wavelengths. In Table A.1, we list the detection of molecules toward the 14 high-mass YSOs, while in Table A.2, we list the hyperfine structure fit results and physical parameters of the dense cores derived from the N2H+ (1−0) and C2H (1−0) lines. In Table A.3, we present continuum fluxes measured for the 14 sources, in the wavelength range from 8.0 μm to 1.2 mm, including data from different facilities: MSX, Spitzer/MIPS, IRAS, Herschel/PACS, Herschel/SPIRE, JCMT, APEX, and IRAM 30 m. Finally, in Fig. A.2 we show the SEDs for the 14 objects, with the observational parameters listed in Table A.3 and the best fit as explained in Sect. 3.3.

Top-left: Hi-GAL 500 μm (or JCMT 850 μm) continuum image in contours overlaid on the Spitzer/IRAC 8.0 μ (or MSX 8.3 μm) image in color scale. The box show the region mapped with the IRAM 30-m telescope. Top-right: nine panels with the zero-order moment (velocity-integrated intensity) maps of different molecular species (labeled in the top-left corner of each panel). The minimum and maximum contour level (in units K km s-1) is indicated in the bottom part of each panel. Bottom: four panels with the IRAM 30-m spectra at 3 mm, covering a frequency range from 87.6 GHz to 93.4 GHz.

Spectral energy distributions for the 14 sources listed in Table 1. Black dots correspond to measured continuum fluxes in the range 8 μm to 1.2 mm (see Table A.3), while the crosses correspond to upper limits. Red dots correspond to the new Hi-GAL data (Molinari et al. 2010a,b). White triangles correspond to IRAS fluxes at 60 μm and 100 μm not considered in the SED fitting when there is available Hi-GAL data. The solid curve represents the best fit to the data points with wavelengths ≥60 μm (see Sect. 3.3).
