Corner plot of the parameter posteriors obtained for the mock galaxy selected in Sect. 4.1.2, illustrating the one- and two-dimensional marginalised posteriors for a subset of the parameter space dimensions (for clarity and visualisation reasons). The shaded grey regions highlight (68%, 95%) confidence from darker to lighter, corresponding to (1-σ, 2-σ). The dashed black lines mark the position of the weighted median value of parameters while the values above the diagonal panels show the median and 68% percentile around the median (roughly corresponding to 1-σ confidence in a Gaussian approximation). As a term of comparison, we also show mark, with orange solid lines, the real value of each parameter.
