Ratio, Δ (re-scaled to 0; see Eq. 16), between input and best-fit values for XRISM Resolve simulations, as a function of the input, N_H. The shaded areas show the corresponding standard deviation. The colour coding corresponds to the different input log(ξ₀) (see legend). From left to right and top to bottom, the different panels correspond to the best-fit distributions of log(ξ),v₀, N_H, θ_out, respectively. For ease of visualisation, we only report the results after the inclusion of the emission component. Note that, in the last panel, only those simulations with inputs of θ_out > 45deg are included.
