Fig. 4, panel (b)

Cooperativity C at maximum transfer efficiency, drawn as closely spaced dots against the effective spin-resonator coupling $g_{\mathrm{eff}}/2\pi$ and the external coupling rate $\kappa_{\mathrm{ext}}/2\pi$, on the printed 0.1 to 1.0 scale. The $g_{\mathrm{eff}}$ values are as deposited, a factor of about $\sqrt{2}$ (1.41) below the printed curve.
