Figure 2
Validation of the particle-classification procedure based on simulation of spheres with different particle sizes and photon intensities. (a) Classification of patterns as nonhits (grey area) and hits (above the black solid line) as function of particle size and intensity. Data points with strong deviations in the size and intensity estimates are depicted in orange; the rest are shown in green and separated by black dashed lines. (b) Distribution of errors in the diffraction centre. (c) Distribution of errors in particle size and intensity (normalized to the simulated intensity). The colour-coding in (b) and (c) follows the categories shown in (a). A statistical summary of the green distributions is given in Table 1. |
