Notes. Energy spectral index from C = CRATES (estimated in the range 0.843/1.4 and 4.85 GHz); S = SPECFIND v.2.0.

^(†)

Fluxes are expressed in units of 10^-11 erg cm^-2 s^-1.

^(*)

The flux reported in parenthesis refers to the peak flux in 20−40 keV band for sources detected through the bursticity analysis (see text for details).

^(‡)

Radio position from the NVSS catalogue (see text).
