Old tight-binding parameter files may be converted to the new version with a Fortran filter . All parameters are subject to change as we improve our fits. The form of the tight-binding parametrization has changed slightly. Each parameter file now has a header which describes the style of parameterization, the elements in the file, their atomic weights and orbital occupation numbers, and the cutoff ranges for each type of interaction. The idea is to move all parameter-dependent information into the parameter file.
More details are available in the documentation for the static program.
The actual parameters have not changed. If you are using an older version of our tight-binding codes, simply strip off the new header to get a version of the parameters which runs with your code. Note, however, that we recommend upgrading to a newer version of the code.
