fitspec is a method to fit the energy and intensity of spin wave modes at specific Q-points (like you would measure using a triple-axis spectrometer).
Internally it callssw_egrid to calculate the scattering intensity swConv. For systems with twins, sw_egridlooks up the twin information in the base spinw obj. However, fitspec calls the original spinw/spinwave method with the fitmode, true flag which means that the base spinw object is not included in the spectrum struct.
We need to either include the spinw object in the spec struct when there is a twin or find some other way to pass on twin information in the spec struct.
