If the program *calcsta* has been set up, the fitting is started
by the command (in the example you should go to the directory */mcphas/examples/cecu2a/fit*)
:

simannfit 10 [-t 1000][-s 100000] [-n 200] mcphas.jjj [and possible other input parameter files].

- The ''10'' in the command means that the initial statistical ''temperature'' of the algorithm is set to 10.
- Option -t sets time limit until program end (in seconds).
- Option -s gives maximal number of iteration steps to be done.
- Option -n allows to store every 200 steps the parametersets in a table in
*results/simannfit.0*. - Option -p 30 probes solution, i.e. runs simannfit , stepwidths are not decreased during
fitting, if parameter set is found with
then all sets par in
*results/simannfit.1*are scanned and distance is calculated. If (=number of parameters) for for all sets par, then is appended to the list in*results/simannfit.1*up to 20 parameters are appended to this list, after that the program stops - in this way a series of equally good solutions can be explored. - option -w 1.4 before starting simannfit, multiply all stepwidths by factor 1.4

The program generates for each parameter a histogram file showing the number of occurrences of a certain parameter value in solutions, where sta decreased.
