Supplemental Materials for <Subspace modelling enabled high-sensitivity X-ray chemical imaging>

We introduce a simple and robust denoising approach to improve the image quality of TXM-XANES, which enables fast and high-sensitivity chemical imaging. This supplemental material contains in-depth analyses of this approach and more experimental results.
