Comparison of projected 2D posterior distributions for the parameters Ω_m and S​₈ as derived from our fiducial setups using two sampling codes – POLYCHORD (solid black line) and MULTINEST (dashed grey line) – against the Planck-2018 results (solid red line). The contours correspond to the 68% and 95% credible intervals and are smoothed using a Gaussian kernel density estimation (KDE) with a bandwidth scaled by a factor of 1.5, made possible by the ChainConsumer package (Hinton 2016).
