﹩S_{\mathrm{NVSS}\,}﹩ vs. ﹩S_{\mathrm{TXS}\,}﹩ for ~30,000 sources common to both surveys. The ~30,000 compact sources common to both the NVSS and the Texas surveys (points) and the sources from this paper (squares) are shown. Also shown are lines are of constant spectral index ﹩\alpha =-\mathrm{log}\,( S_{\mathrm{NVSS}\,}/ S_{\mathrm{TXS}\,}) / \mathrm{log}\,( 1400/ 365) ﹩, for ﹩\alpha =-1.5﹩, −1.0, …, 1.5. The points above the line ﹩\alpha =1.5﹩ that are not squares were removed from the sample because of confusion, lobe‐shifts, etc. The dashed line is at ﹩S_{\mathrm{TXS}\,}=200﹩ mJy, and we are complete for sources above this line (with ﹩\alpha \geq 1.5﹩, of course).
