Notes. The columns correspond to the galaxy name, the spectral indices of the radio (αt), IR-to-optical/UV (α0) and X-ray components (αx), the turnover frequencies (νb and νx) and their associated fluxes (Sνb and Sνx). The different spectral components of the broken power-law distribution used to fit the continuum spectra are indicated for the case of the Sombrero galaxy in the upper left panel of Fig. 2.
