Amplitude of Best-Fit Spectrum	> Amplitude of Participant Spectrum	Penalty

¹Rigid constraints are restrictions on the fit such that if the value being constrained is out of range, those fit parameters are rejected by the algorithm. The fit algorithm will go back to the previous set of fit parameters and will continue the search for a minimum in another direction

²Penalties are constraints where if the value being constrained is out of range, a fixed penalty value is added to the X² value for each instance where the fit value is out of range to artificially indicate that the fit is not good
