Average abundance ratio with respect to iron within R₅₀₀ at z ∼ 0.1 over the cluster sample for z = 0.1 (left) and z = 1 (right) recovered using 100 ks observations. The input abundance ratio are shown as histogram bars filled with the respective contributions of SN_Ia (blue), SN_cc (magenta) and AGB stars (yellow), computed from the outputs of the hydrodynamical simulation presented in Sect. 2. For z = 1, carbon (C) and nitrogen (N) are not shown as the lines are outside the energy bandpass of the instrument (not fitted).
