SixPACK
Abstract
Sam's Interface for XAS Package, or SixPACK for short, is the unification of the previously named SamXAS and SamView programs into a single analysis package. Thus the package can guide the user through data averaging and calibration, background removal, and many aspects of fitting. The interface builds on Matt Newville's IFEFFIT engine. It contains six basic modules:
SamView - an interface for averaging, calibrating, and deadtime correcting raw data
- Background subtraction of data to create normalized mu(E) and chi(k) functions
- A FEFF periodic table interface to create single scattering phase and amplitude paths - Now compatible with FEFF6 through FEFF8.
- A GUI for the fitting of experimental EXAFS to theoretically derived phase and amplitude files
- A GUI for linear combination fitting of EXAFS or XANES to experimentally obtained reference spectra
- A principal component analysis routine that decomposes data into a set of orthogonal components. Also features a target transformation feature to check if potential reference spectra are in the component space defined by the samples.
