Classification of hits based on fitting to a sphere diffraction model. (a) Distribution of particle sizes and incident photon intensities shown as a two-dimensional histogram. The solid/dashed grey lines indicate the same detection/classification limits as described in Fig. 2[link]. The size of a diameter bin was chosen to be 4 nm, while in the intensity direction 50 bins have been logarithmically distributed between 109 and 1013 photons µm−2. (b) Distribution of particle sizes (integrated inside the red rectangle along the vertical direction) shown as a histogram with a bin size of 2 nm and a Gaussian kernel density estimation (KDE) with a bandwidth of 0.025.
