This is for an anomalous difference map, i.e. (F(obs)+)-(F(obs)-) with
F(calc) phases, weighted with FOM (refinement). Is this what you want?

This is a fairly new feature. If the anomalous difference map doesn't
show peaks where you expect them we'd have to check the algorithm
generating the coefficients.
