Comparison of the parameter posteriors for three different sets of FRB mocks, i.e., with 100 (black), 500 (green) and 1000 (orange) samples. The diagonal panels show the 1D posterior probability distribution, and the off diagonal panels show the joint 2D posteriors. The contours represent the 68% and 95% confidence intervals. The dashed line represents the input parameter values used to generate the reioniza-tion model, which has further been used to create the FRB mocks.
