Curve fitting utilities
||A Windows program
providing an interface for single or multiple curve fitting. The
program requires the library MultiFit.
||A text-based program
for Windows (EasyWin) and Unix, providing an interface for single
or multiple curve fitting. The program requires the library
||A C++ source of
a library for single or multiple curve fitting.
The library is required
by WinFit and XFit, but it can also be used by other programs.
This is a
program for LINUX computers for
simulating and fitting of specular and diffuse neutron
reflectivity data obtained with polarized or
non-polarized neutrons on
magnetic or non-magnetic samples.
This program is based on the combination
of the Supermatrix Method and the Distorted Wave Born
This is an ANSI-C program which uses the MINUIT (CERN)
minimizing routine (c-minuit).
mfit is a related general purpose minimizing program.
At present the following problems are covered:
- X-ray reflectivity from a rough multilayer
according to the Parratt formalism described in Ref. .
- Polarized neutron reflectivity from a
according to the super-matrix formalism described in Ref. .

Data handling utilities
||ScanRead is a
Windows95 program for reading Spec, Tascom and ASCII data files,
for instant scientific plots of the data and for extracting scans
to ASCII files for subsequent analysis. In addition, detailed
about how to combine ScanRead with the scientific graphics program
Microcal Origin (TM) is provided, as well as some sample Origin
macros for data analysis.

a professional version of the ScanRead program. In addition to all
of the features of its predecessor, ScanRead-PRO includes powerful
new options, such as the ability to automatically export the contents
of all scans into a numbered sequence of ASCII data files.
||LindePlot is a
scientific data presentation tool for Windows95/98/NT/2000, in order
to make XY-plots in which the data appear slowly on the plot, one
point at a time, at a user-controlled speed. This program can be
especially useful for real-time presentations during
||XSW is a Microsoft
Windows95/98/NT/2000 program to read, plot, and perform basic
on datafiles produced by the Perkin-Elmer XPS-Surface Analysis
program (ver. 3.1S). It is particularly useful in order to facilitate
ultrafast real-time data evaluation during x-ray standing
In particular, useful features include the ability to quickly step
through XPS/Auger photoelectron spectrum, obtaining the peak heights
and background levels for literally hundreds of peaks, just with
a few clicks of the mouse!
These are ANSI-C programs for LINUX computers for
the combined visualisation of the series of 1D
plots generated during a reflectivity scan (offspecular)
or during a general four-circle scan (mythen) using the
Mythen linear PSD.
Analysis of time-resolved diffraction data
This is an ANSI-C program for LINUX computers for
the calculation and visualisation of the distribution
of the magnetic fields generated by iron-free cylindrical
