Notes. Exponents are given in parentheses, e.g., 1.4(16) = 1.4 × 1016. The errors of the continuum parameters are indicated by subscript (left) and superscript (right) values, e.g., is the lower limit of 3.7 × 10+24 − 1.2 × 10+00 and 3.7 × 10+24 + 1.6 × 10+00 is the upper limit of the corresponding hydrogen column density of 3.7 × 10+24. For sources marked with an asterisk (*), we could not derive a self-consistent description of the continuum of the corresponding core spectrum. Here Tdust indicates the dust temperature in K, NH,dust the hydrogen column density in cm−2, and βdust the power-law index of the dust emissivity. We use temperature units for the fitting. Therefore, the spectral indices for flux units α is given by α = β + 2. Additionally, γdust describes the contribution of dust to the total continuum of the corresponding core spectrum in %, Te the electron temperature in K, EM the emission measure in pc cm−6, and γff the free-free contribution to the total continuum in %.
