Corner plot derived from the MCMC fitting of the Lyα line (see Sect. 4.1). In this figure we only show the correlation between the absorption parameters, namely z_i, b_i, and N_C IVi, which are the fitted redshifts, Doppler parameters (in units of km s⁻¹), and column densities (logarithmic) of the eight H I absorbers. The black dotted lines in each of the histograms represent 15.8 and 84.2 percentiles, which correspond to the reported uncertainty ranges. The blue solid lines mark the median and reported fit values, respectively.
