Fig. B.4.


Corner plots of the relative error on parameter (Xfit − Xinp)/Xinp = ΔX/Xinp as function of parameter (Yfit − Yinp)/Yinp = ΔY/Yinp, for the spectroscopic temperature, Tsl, oxygen, silicon, and iron abundance, redshift, z, and the normalisation 𝒩, for cluster C4. The diagonal panels are the corresponding relative error distribution, where the red solid line indicates the Gaussian best fit of the distribution (parameters μΔP, σΔP given above) and the dotted line is the value of μΔP ± μfit. Top Broad-band fit. Bottom: multi-band fit (Sect. 4.6) considering a spectroscopic temperature.
