Fig. 2, panel (a)

Optimal average spin-squeezing parameter $\xi^2_m$ against atom number $N$, on log-log axes, for the conditional dynamics at $\epsilon = 0.017$, $d = 0$, $\phi = 0$ and $\eta = 1$: Full dynamics (circles), 2nd order (squares) and 3rd order (diamonds), with error bars. The dashed curve is the second-order asymptotic result and the horizontal dashed line the standard quantum limit (SQL).
