RGS1 (top panel) and RGS2 (bottom panel) instrumental response models for the O VII ﹩z=0{\mbox{--}} 0.5﹩ region, as a function of wavelength (upper axes) and redshift relative to ﹩\lambda =21.602﹩ Å (lower axes); a strong ﹩z=0.25﹩ line with ﹩N_{\mathrm{O}\,\,{}^{{\rm{\small VII}}}}=10^{16}﹩ cm⁻² (﹩W_{\lambda }=36﹩ mÅ) is shown for reference.
