Fc doesn't contain the weighting scheme used in the creation of the map
coefficients, so Fc would require some sort of program to be run to
recreate those for both 2Fo-Fc and Fo-Fc maps. By which time you might
as well run a single cycle of the refinement program in question to
generate new map coefficients - so I don't see the benefit of Fc.
The map coefficients, on the other hand, are a checkpoint of the maps
being looked at by the author at the time of deposition and don't
require programs beyond a typical visualization program (i.e. Coot) to view.

It seems that deposition of map coefficients is a good idea.
Does someone have an mtz2cif that can handle this?
Maybe I missed something.
What is accomplished by depositing map coefficients that isn't
done better by depositing Fo and Fc?
