Flowchart of the data analysis used to obtain E at various indentation depths and postprocessing with height correction of E for a given E-map. The raw data files were analyzed three times at three different indentation depths. The analysis ended when all data points in the E-map were analyzed and three results files were written for a given E-map. Postprocessing utilized these three results files and selected the proper results file for a given pixel based on cell height information, and then corrected this value by multiplying with the factors shown depending on the specific tip geometry.
