Question: Problem with inconstant integration of probablity

At line 46 I do some integrals of a probablity function obainted from complex amplitudes. The plot of the function is shown above. However, the integral suddlenly drops to almost nothing when I increase the limits from +/- 0.195 to +/-0.2. The transition actually occus at ~0.196 (not shown)

This makes no sense. It doesn't seem  from the plot that the step size could get so large as to miss the peak! However, I don't know how to change numerical integral step size to test that.
