Fig. 7.
Photon noise sensitivity of the PESCC and SCC for wavefront sensing. The reported photon number is the number of photons before the coronagraph. The error bars show the 1σ deviation over the 100 random wavefront aberration instances. The dashed and dotted lines show 
fits for photon numbers ≥1011 to show the regimes in which the performance is photon noise-limited.
