Notes.

Column 8 reports the fitted spectral index. The regions defined for H1 and H2 roughly cover their total extensions and flux densities are therefore total values. Flux densities of H3 are instead local values, obtained as the sum of the measurements within the considered boxes. Uncertainties on α for H1, H2, and inner H3 are fitting errors; the uncertainty on α for outer H3 is derived from the standard formula for the error propagation as in Eq. (A.1).
