Dependence of fitted HBT radii on fit range for two analyses (w/ and w/o electron cut)

• the most central AuAu@19.6 GeV collisions (bin1)
• Coulomb radius - 4 fm

There are some empty stops on the plot below. It's because for some kT bin and fit ranges the fit failed.
In general I could make this fit working good just by changing initial conditions but here I decided to keep the fit conditions unchanged for the purpose of the study of fit results' discrepancy.
