How a seemingly innocent question can explode ...
Well there seems to be a widespread misunderstanding
For comparison I repeated my previous calculation using the flat
(non-Wilson) prior that you suggested (you would get the same results
using the FW method in the limit of an infinite WDP). So now the
results are indeed totally independent of the WDP - but IMO the results
are also completely
diffraction limits are roughly isotropic, in certain
resolution shells isotropy is still a bad assumption.

Dear Experts,
At the risk of exposing excess ignorance, truncate makes me
very nervous because I don't quite get exactly what it is
doing with my data and what its assumptions are.

I believe also that in an earlier posting Peter Zwart said he thought
that CNS doesn't take account of the Wilson distribution when doing its
version of the correction; if this is true (and I have no independent
evidence that it is since I'm not a CNS user), then the above argument
