Detailed Description

Fitted parameters and errors for one peak.

Every field defaults to -1, which is also what a failed fit leaves behind — check FitResult::valid rather than testing individual members.

Warning
Amplitude semantics differ between the two backends, and nothing in the type says which you are holding. FittingUtils fills these with peak heights in counts; RooFitUtils fills them with RooFit yields (event counts). Mixing them up produces numbers that look plausible and are wrong by the normalisation. The ratio component_amplitude / gaus_amplitude is the one quantity that means the same thing in both, which is what makes constrained fits portable between them.
