Figure 2
(a) A single-crystal diffraction frame obtained from insulin with a Pilatus 6M detector with (b) the azimuthally averaged signal before and after clipping data. (c) Uncertainties when calculated assuming a Poissonian error model (orange, red) or when measuring the deviation within all pixels in a ring (green, blue). (d) A histogram of intensities for two rings at r = 87 mm and r = 160 mm from the beam center with the distribution fitted as Gaussian curves: [g(x)\propto \exp[-{{(x-\mu)^{2}} / {2\sigma^{2}}}]].
