SEDCORR: An Algorithm for Correcting Systematic Energy Deficits in the Atom Probe Mass Spectra
SEDCORR is an open-source Python module designed to correct for the systematic energy deficits in atom probe mass spectra of electrically insulating samples. The assumption of the algorithm is that the mass spectrum for a dataset is conserved throughout the dataset and that any changes to the peak positions arise from an unknown slowly-fluctuating accelerating voltage. For computational speed, the unknown accelerating voltage is determined using a template matching FFT-based cross correlation method. The Python source code and an example dataset is available on the home page: https://github.com/usnistgov/SEDcorr
