Pick up data points from the screen, dump numerical values.Often one is
interested in extracting the numerical values of data, which are only
available as data points in a figure. Display the figure on the screen,
start PICKDATA and click on the data points. The numerical values will
be written to a file. The programm runs on WINDOWS versions with a
transparency option of the windows or under WINE on Linux. (For WINDOWS
XP this feature is provided by add-ons; from VISTA on, transpareny is a
standard option. On Linux, the terminal command transset -c

2-dimensional Langevin code
is a demonstration of the numerical solution of the Langevin equations
in two dimensions, the elongation and the mass asymmetry in fission.
The dissipation strength and the temperature can be varied.
The code runs on Windows or under Wine on Linux. The program is written
in JBasic .
The zip file
contains the code and the JBasic run-time library. Start the program by

INSTALLING THE EXECUTABLE PACKAGE AND STARTING CONFID:
1. Download the zip file and unpack all files in one folder.
2. Start CONFID by running confid.bat
in a command window.

A computer code for matching the information from incomplete
experimental data and a model calculation.
The following information is required:
MATCH code constructs two likelihood functions from the experimental
and the calculated multi-variate distributions and determines the
maximum of the weighted sum of the log-likelihood functions. A few
parameters allow to adjust the influences of the experimental
data and of the model values and correlations individually to optimize

uncertainties. The data can be incomplete.

- Corresponding covariance matrix (2-dimensional) from the
The code can be used to determines a complete
distribution which is consistent with the experimental data
considering the theoretical constraints by the correlations between the
data points from the calculated covariance matrix.
