Plot showing how the intrinsic LF would differ (in terms of the standard deviation σ) from the SDSS one (Jiang et al. 2016) if an additional number ﹩i\lt 52﹩ of quasars in the sample are lensed. Blue points are the results for a single trial, the black line is the average over 10⁶ trials, the shaded region indicates the 1σ uncertainty.
