Distributions of a) centimeter luminosity; b) Lyman continuum; c) spectral index; d) electron density; e) emission measure; f) ionized gas mass; g) linear radius of the centimeter source; h) deconvolved angular diameter, θ_S; and i) peak intensity to flux density ratio, for the centimeter sources detected with ATCA. The numbers at the top of each panel indicate the total number of sources used in the histogram (in some cases we could only use 207 sources, i.e., those with distance determination), and the mean, standard deviation and median values. The vertical dashed line indicates the median value.
