ViPErLEED is an open-source package for quantitative low-energy electron diffraction, also known as LEED-I(V). It comprises tools for measurement, processing, and analysis of LEED-I(V) results, calculation of theoretical I(V) curves based on a structural model of a surface, and optimization of such a model to best fit the experimental results.
