Statistical outcome of the PL-distributed MC parameter space selection. The Δ_p-versus-${\gamma }_{\mathrm{cut}}^{\min .\mathrm{ratio}}$ parameter space is shown in the top panels, whilst the bottom panels show the Δ_p-versus-r_min parameter space. The three columns refer to the selected f_γcut PDF. The blue crosses mark the total MC parameter space, and the filled circles the best sample parameter space. The color scale marks the ratio of the volume of best parameter space, at the coordinate reported on the x and y axes, to the total MC parameter space; both volume sizes refer to the given f_γcut PDF. The red boxes mark the parameter space where the MC-averaged 1-σ dispersion of the X-ray EVPA is < 25°.
