Dear John,
I would say that in that case the FoFc is basically flat.

Dear Pierre,
I was in particular talking of 2FoFc refinement maps.
In the attached picture for example you can see the 2FoFc map contoured at 1
sigma level

Dear Vito,
We accumulated quite a good deal of knowledge of this type of complex, firstly
the platins, then later, led by Dr Alice Brink, rhenium complexes with
proteins. This review describes some of this:-

Dear All,
many of us have probably experienced that, in the diffraction
of protein ligands containing heavy atoms (cisPt, I3C, etc), the
overwhelming electron density of the metal can totally flatten that of the
light atoms around (or rather make it look insignificant).
