Curve fitting utilities
| WinFit | A Windows program providing an interface for single or multiple curve fitting. The program requires the library MultiFit. |
| XFit | A text-based program for Windows (EasyWin) and Unix, providing an interface for single or multiple curve fitting. The program requires the library MultiFit. |
| MultiFit | 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. |
| Superfit |
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
Approximation.
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. [1].
- Polarized neutron reflectivity from a
magnetic multilayer
according to the super-matrix formalism described in Ref. [2].

Data handling utilities
| ScanRead | 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
information
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. Article in "Lasers & Optronics Magazine"; August 2000 Article in "Reseach & Development Magazine Online" |
| ScanRead-PRO | ScanRead-PRO is
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 | 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
meetings/talks/seminars/etc. |
| XSW | XSW is a Microsoft
Windows95/98/NT/2000 program to read, plot, and perform basic
analysis
on datafiles produced by the Perkin-Elmer XPS-Surface Analysis
software
program (ver. 3.1S). It is particularly useful in order to facilitate
ultrafast real-time data evaluation during x-ray standing
wave experiments.
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! |
Image Analysis
| DataPlot |
A program for STM/AFM/2D-XRD/2D-Neutron data analysis. |
| DataScan |
DataScan-for-Java:
A Java-based "open source" software package for topographic
image analysis, particularly for images such as from scanning probe microscopies (STM, AFM, etc.) as well as for x-ray and neutron diffraction (position sensitive detectors, CCD detectors, etc.). The source code is easy to modify, and the authors encourage active collaboration!

| Mythen |
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
|
file_read 2Dfit |
These are ANSI-C programs for LINUX computers for the
analysis of the time-resolved experimental results
obtained at the surface diffraction beamline of the
Max-Planck-Institut fuer Metallforschung at the ANKA
synchrotron facility in Karlsruhe.

Magnetic-field calculations
| Spule |
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
concentric coils |
