back to fit

 

The fitting procedure will store temporary best-fit parameters in the file ~tmppars.* (in the data directory, with the same extension as the data files) to allow restoring the analysis in case of a crash of the program. Sometimes, the cause of the crash is a floating parameter that does not influence the quality of the fit, and therefore can assume an unlimited number, causing the crash.  In this case, when reloading the data, the attempt to restore the fit will fail.  However, the tmppars file can be edited with the notepad, and the parameter with the very large number can be set to 1.000000

 

The following format for the ~tmppars file is used:
