Notes. Column (2): True values of the population parameters. Column (3): Values of the lens population parameters, obtained by fitting the model of Eq. (17) to the sample of detected strong lenses. Column (4): Priors on the parameters. Column (5): Median and 68% credible interval of the marginal posterior probability distribution of each parameter. Column (6): Inference with individual source redshift information.
