FitSuite  2.0.0

Program Overview

FitSuite is an environment for simultaneous fitting and/or simulation of experimental data of vector-scalar type, such as parametric curves and surfaces typically collected in a physics experiment. “Simultaneous” here means that several sets of the same type of experiment and even of different types of experiments can be simulated/fitted in a self-consistent, statistically correct framework with provisions for cross-correlation of the theoretical and specimen parameters.

Starting in 2004 (as part of the Dynasync FP6 project sponsored by the European Commission, and since 2005, within the NAP_VENEUS project, sponsored by the Hungarian National Office for Research and Technology) we developed FitSuite for Windows and Linux, a code that consistently handles by now data of over ten spectroscopic methods with over twenty theories together with a large number of sample structures in a common inter-related framework.

The original idea of cross-correlation and of hierarchy of theories as well as a number of subroutines of FitSuite were inherited from EFFI (Environment For FItting), an originally Mössbauer spectroscopy-related FORTRAN program developed over the last two decades by Prof. Hartmut Spiering from University of Mainz. In view of the friendly and fruitful collaboration between the Budapest and Mainz groups over the last decades, Prof. Spiering kindly agreed to build in the theories written by him and tested within EFFI into FitSuite in order to promote both projects. Enlightening discussions with him greatly promoted the FitSuite project. Although in the last three years the two projects developed in different directions, we are very grateful for Prof. Spiering’s essential contribution to FitSuite.
