Spectral indices of the SEDs presented in Fig. 8 obtained considering a cloud with central density nC = 105 H cm−3 (Eq. (2)). From top to bottom: the spectral indices are computed between ALMA bands 6 and 7 (centred at 1.3 and 0.87 mm, respectively), ALMA bands 3 and 4 (centred at 2.8 and 1.9 mm, respectively), ALMA band 3 and VLA K band at 23 GHz (≡1.3 cm), and ALMA band 3 and VLA X band at 12 GHz (≡2.5 cm). Same colour code as in Fig. 3 for the grain composition. Left: cloud externally illuminated by the standard ISRF alone. Right: cloud with an additional internal heating source (see Sect. 2.3 for details).
