The radio spectral index distribution of the CHILES Con Pol radio continuum sources. The peak of the histogram is placed on α = −0.725, implying that the majority of microjansky radio sources are dominated by star formation. Panels (B)–(G) display histograms of the spectral index for different S/N cuts, e.g., 7, 10, 15, 20, 25, and 30.
