◆ FWHMErr()

Double_t TSinglePeak::FWHMErr ( )

Return the uncertainty in the full width at half-maximum. Since it is complicated to do this without knowledge of the underlying fit function, we simply assume that the (relative) uncertainty in the FWHM is the same as the uncertainty in sigma.

This function checks if a parameter or its limits have been set to a non-zero value. In case that the user fixed a parameter to be zero, the limits are non-zero, so this case is covered as well.
