 This should improve the structure features at the F1 head domain, but the FSC resolution does not necessarily improve here. Because the even/odd half set only are only aligned to the "neutral" struture of their half-set and never see each other, there is a possiblity that they converge to slightly different states, and the FSC resolution decrease even though the feature in each half-set improves. This is less of a problem in datasets with more particles since the "neutral" state would be better defined, but here there are some uncertainties with only 5 tomograms... This should improve the structure features at the F1 head domain, but the FSC resolution does not necessarily improve here.

-Finally, we can refine the local motion of the F1 domain a bit more, without the neural network part. Depending on the particle count and the type of motion, this sometimes improve the resolution of the target domain.
