Posterior distribution from MultiNest plotted with two-dimensional histograms comparing each pair of free parameters of the hot-model (N_H, k_B T, v and σ_v) in the four upper distributions, together with the free parameters of the xabs-model (N_H, v, σ_v and log ξ; for clarity, we show only the logξ of observation 008411) in the four lower distributions. The contours indicate the 1σ, 2σ, 3σ, and 4σ confidence intervals in two-dimensional space. The hydrogen column densities N_H are expressed in units of 10²⁴cm⁻².
