Data analysis in spectroscopic STXM
Matthew A. Marcus
Abstract
The typical output of a STXM (Scanning Transmission X-ray (spectro)Microscopy) measurement is a data cube consisting of a set of images (measurements of X-ray transmission at a grid of pixels) taken at a sequence of incident energies. As with any experimental measurement, this raw data must be reduced to some standard form and interpreted. In this paper, I review the basics of how to go from raw data to information about the sample. I will discuss the fundamentals of X-ray spectromicroscopy, data reduction, descriptive and model-based analysis, and available software, with examples taken from the literature.
