SED-fitting analysis. The panels show the SED decomposition for the different regions (indicated in the top-left corner) discussed in Sect. 4. The observed measurements, shown by orange points with their uncertainties (±3σ) have been modelled using DustemWrap. The three fitted components: dust (in orange), synchrotron (in blue), and free-free (in green) are shown with shaded area indicating their range, assuming two different spectral index values.
