Fig. 4, panel (1)

Fisher information $\mathcal{F}$ against $\eta_i$ at $\eta_s = 0.89$, the upper plot: $\mathcal{F}_{\mathrm{TMSV}}$ (theory, with its 68% band), $\mathcal{F}_{\mathrm{TMSV\_Poly}}$ (direct estimation from the data, markers) and $\mathcal{F}_{\mathrm{CO}}$ (coherent state). The printed 68% error bars of the markers are drawn as a band, the dB labels are left out, and the inset is its own panel.
