 EasyLEED facilitates data analysis of images obtained by low-energy electron diffraction, a common technique in surface science. It aims to automate the process of extracting intensity-energy spectra from a series of diffraction patterns acquired at different beam energies. At its core a tracking algorithm exploiting the specifics of the underlying physics (see [paper](http://dx.doi.org/10.1016/j.cpc.2012.02.019)) allows to link the position of the diffraction maxima between subsequent images.
