Description
If at least one coherent amplitude and more than one incoherent amplitude are included in the signal model then the fit fractions are nonsensical.
This is caused by a missing continue on line 1843 of LauIsobarDynamics.cc which leads to array elements being accessed in fifjSum_ and fifjEffSum_ beyond the sizes of these arrays (first incoherent term works by fluke due to null terminators on the arrays).
The IFFs between the coherent terms and all but the first incoherent term are calculated incorrectly (large negative numbers). This causes the DPrate to be calculated incorrectly (large negative number) so all fit fractions come out with nonsensical values (small positive numbers).
