IFEFFIT is an interactive program for XAFS analysis. It combines the high-quality analysis algorithms of AUTOBK and FEFFIT with graphical display of XAFS data and general data manipulation.

IFEFFIT comes as a command-line program, but the underlying functionality is available as a programming library. The IFEFFIT library can be used from C, Fortran, Tcl, and Perl.

PyMca is set of applications and Python libraries for analysis of X-ray fluorescence spectra.

The applications included in this package are:

• edfviewer - Display and inspection of data files in ESRF Data Format
• elementsinfo - Displays element specific X-ray data
• mca2edf - Converts files from SPEC MCA format to EDF
• peakidentifier - Displays X-ray fluorescence peaks in a given energy range
• pymcabatch - Batch fitting of spectra
• pymcapostbatch - Post-processing of batch fitting results
• pymca - Interactive data-analysis
• pymcaroitool - Region-of-interest (ROI) imaging tool

The PyMca toolkit can read data files in SPEC, ESRF data file (EDF), OMNIC, HDF5, AIFIRA and SupaVisio formats.

This are the scripts of the package.

Larch is a library and set of applications for processing and analyzing X-ray absorption and fluorescence spectroscopy data and X-ray fluorescence and diffraction image data from synchrotron beamlines.

Larch is especially focussed on X-ray absorption fine-structure spectroscopy (XAFS) including X-ray absorption near-edge spectroscopy (XANES) and extended X-ray absorption fine-structure spectroscopy (EXAFS). It also supports visualization and analysis tools for X-ray fluorescence (XRF) spectra and XRF and X-ray diffraction (XRD) images as collected at scanning X-ray microprobe beamlines.

This package installs the larch module and scripts for Python 3.

• GSE MapViewer for GSECARS X-ray microprobe data.
• Larch CLI and Gtk GUI.
• XAS Viewer for XAFS Processing and Analysis.
• XRF Display to display and analyze XRF Spectra.

The Larch CLI is available as larch_cli in Debian.
