Dear Marcus,
thanks for the hint to your recent loop paper. I browsed through it but I stumbled already on page three where you outline your philosophy: You want to test, how close you can fit a potential field to a set of (stereoscopically derived) field lines. The answer could have bee given without numerical tests: as close as your parameter space allows. The same would hold for a NLFField. The field you find is probably not unique, because you may superpose potential fields which vanish along the field lines. Hence from a successful fit no conclusion can be drawn about the nature of the true field. At the end of subsection 2.1: I do not know the paper by Gary (2010), but Conlon and Gallagher (2010) is not NLFFF. And finally: What do you mean by "Abelian"? Commonly this term is used for a group property indicating the the group operation is commutative. What does "Abelian" mean for a magnetic vector field ?
Many regards
Bernd
