Towards a black-box for biological EXAFS data analysis – III. A universal post-processor for fluorescence XAS: KEMP2

Because of the typically rather low trace element concentrations in biological samples XAS is collected in fluorescence mode with the help of a multi-element detector. In addition, several scans have to be accumulated and thus post-processing operations have to be carried out after the measurement, e.g. selecting good detector channels, checking for radiation damage, fitting of background and normalization. KEMP2 is a freely available post-processor implementing all these steps, while maintaining universal applicability by separating the instrument- and beamline-dependent steps like energy-calibration etc. from XAS-generic tasks. Thus, KEMP2 has the potential to serve as a highly automated data pipeline assisting both senior and novice users.
