Short wavelength Free-electron lasers (FELs) allow imaging of individual nano particles in free flight. In laser-cluster interaction studies, single-cluster imaging can be used to sort the single-shot measurement of reaction products (e.g. ions, electrons) by cluster size. The large data sets require automated analysis, often challenging due to detector geometries and noisy background signal. An automated size determination algorithm based on Mie-fits will be presented and the measured size distribution from large xenon clusters imaged at the FLASH FEL will be discussed.
