elemental information.Step-wise normalization is valid in terms of keeping physical interpretation if we are picking out components from the processed SI, but is generally not valid if we use standard EELS edge library.This step-wise operation is demonstrated in Fig. 2, where the component mapping is calculated using the whole energy range.Step-wise calculation with a subset of the energy range might be used to show featured phases with better definition.
