Fraction of BALQSOs which are LoBALs, as a function of radio luminosity. We have included fractions as a function of both LoTSS and FIRST powers. To aid the comparison, we have shifted the LoTSS radio luminosity abscissa by an amount equivalent to the median spectral index between the LoTSS/FIRST samples. Both observed and adjusted FIRST values are plotted, where the adjusted values have been reduced by the fraction of DR7 FIRST detections to LoTSS/FIRST cross-matched detections.
