calibration. To describe part of a measured spectrum, the fitting function must contain a number of such functions, one for each peak. For 10 elements and 2 peaks PyMca and its fitting engine already implement most of the needs of x-ray fluorescence spectroscopy. It is fast (~1 second per complex

Configuration and calibration fits were developed in PyMca including input measures including incident X‐ray beam energy, detector type, and instrumental geometry. The XRF‐FP concentrations were directly obtained from the software, normalized to I 0 , and correlated to the concentration values of the reference method (AAS) for all 153 seed samples (calibration set and validation set).

From PyMca what you can do is to look at the information associated to the different files (open one of your EDF files in the main window and click on the icon providing the information, that icon sometimes has an I, sometimes a bulb on it depending on the platform). One way to proceed in such cases is to use anchors. Anchors are simply channels that will remain fixed during the stripping procedure. That feature is avaible from PyMca version 4.0.9 on. Since the energy calibration can change during the fitting procedure, anchors have to be given in channels and not in energy.

Import Data 2. Calibrate Spectrum 3. Do an advanced fit on spectrum However, regardless of what I calibrate the spectrum too, after it fits the data it is under a new calibration. I.e. my original data is shifting around. Therefore my question is whether or not PyMca performs a calibration automatically when it does a curve fit.
