Ah yes, as you (and Andy Herbert) have pointed out, if we knew the given
dimension was folded (which like I said, I think Analysis currently does
not) and if the aliasing was correct for the peak (so an aliasing of 1 or
3 or 5 or ...) then we would know that that peak was folded. So in theory
we ought to be able to correct for this. Which means that we need to get
folding into Analysis (and as I'm sure has been mentioned long ago, the
display ought to show this as well).
