Overview of raw (spectral-)image data acquired, processing and data generated by PARC. Processing steps are indicated with arrows and italic text in the flow-chart. Numbers in parentheses indicate relevant text sections providing more detail as follows: 4.2 = “Raw data acquisition”; 5 = “Data analysis”; 5.1 = “Phase distribution maps from spectral imaging data”; 5.2 = “Confirmation of phase identity with QXRD”; 5.3 = “Defining grain populations”; 6 = “Results and discussion”; 6.1 = “Source apportionment of grain populations”. References to associated figures and tables are given. Key to outlines in flow-chart: single solid line = image/image stack; double solid line = segmented image (map); single dashed line = derived information. Data produced per PARC group are listed under the relevant grain/grain population/field mask used to collate pixels. The number of PARC groups, grain populations and source/material categories in the processing is indicated (including unclassified). Number of pixels and grains varies per dataset and the numbers shown are approximate indications only. 3D-LOM is included in the overview for completeness but is not further used in the data processing described here
