The calculated 5σ contrast curve for our observation is shown in purple, which was obtained using closure phases. The analogous simulated observation is shown in light purple, which was optimistic by ∼1–2 mag. The IWA for AMI observations is essentially 0.5λ/D (the Michelson diffraction limit). Separations below this limit are therefore grayed out. Calculating the mean and the standard deviation of the contrast curve at separations ≥0.5λ/D gives a value of Δm = 7.62 ± 0.13. This is the contrast we report for this work.
