Notes. Summary of the results obtained for the bright sample (left columns; see Sect. 3) and the lower-luminosity faint sample (right columns; see Sect. 5). We report the redshift range, the number of sources, the number (and fraction) of sources with a flat (α < 0.5) radio spectrum, and for the bright sample alone, the number of extended radio sources. The uncertainties are estimated by adopting the Poisson statistic.
