the formating of fixed parameters (step=0) where wrongly formatted (connected to MUSR-167). This should be done correctly now.

@ -12,6 +12,8 @@ NEW any2many: an attempt to write the universial musr-data-file converter. Just
NEW musrt0: added the possibility to show the t0 saved in the data file 's'. Furthermore added the option
--getT0FromPromptPeak, -g with <firstGoodBinOffset>: will, in non-interactive mode estimate the t0's from
the prompt peak and write it into the msr-file (MUSR-133).
FIXED the formating of fixed parameters (step=0) where wrongly formatted (connected to MUSR-167). This
should be done correctly now.
FIXED for single histogram fits, the chisq given was wrong (not the fit-result though). I missed some needed scaling
when normalizing to 1/ns rather than bins. The same is true for log max. likelihood. I am rather depressed that
nobody so far found this but only R. Scheuermann pointed out there might be a problem.
