Results of the spectral fitting procedure for the target #44909 on the left panels and the target #43977 on the right panels. Top panels: corner plots showing the one- and two-dimensional posterior probability distributions for all the parameters derived from the MCMC algorithm. The contours correspond to the 68%, 95%, and 99% confidence levels, and the best-fit parameter values are also labeled. Bottom panels: the black curves are the observed MUSE spectra in the Ca II wavelength region, plotted together with the corresponding best-fit synthetic models shown by the solid blue and red curves for the targets #44909 and #43977, respectively. The shaded blue and red regions represent the solutions within the 1σ confidence level.
