In some table 1 of the crystallography paper, there is an
item called "FOM". Will you please explain the meaning of it?
Do we have a server to get it or some other route to get this
value?
This is the letter "m" in Randy's 2mFo-DFc map -;)
phenix.refine, phenix.maps and other relevant tools estimate it in
resolution shells using test reflections as described here:
J. Appl. Cryst. (1996). 29, 741-744
and here
Acta Cryst. (1995). A51, 880-887
Of course there are plenty of other literature on this subject!
