Fig. 4, panel (d)

Combined number and phase variance $V(\epsilon_\phi) \times 2\langle n \rangle + V(\epsilon_n)/2\langle n \rangle$ of NP states against average phonon number $\langle n \rangle$ (log-log): squares with one-SD error bars and shaded band, the expected variance of the target NP state (red dashed) and SQL$^*$ (black dashed). Insets are d-inset-1 and d-inset-2.
