Fraction of MCMC realisations per bin that resulted in one object being recovered in a sample with the same size as the effective DR2 sample size as a function of the late-time CSM interaction fraction. The best and worst case scenario for each object is shown in blue and red, respectively. A skewed normal distribution fit with a 1σ uncertainty band is shown for each scenario, and the dashed and dotted lines give maximum and 68% confidence interval of these distributions, respectively. The distributions continue on the right side of each plot.
