Measurements of the effects of missing central speckles in the measured diffraction intensities. Shown here are both the signal-to-noise ratio with unconstrained modes removed (red curve), and Rreal calculated before (grey curve) and after (black curve) removal of unconstrained missing modes. The results are shown for the same size simulated cell in a smaller array (σ = 4.6) at left, and a larger array (σ = 7.5) at right.
