when you run
phenix.real_space_correlation m.pdb d.mtz
it will calculate and output map correlation coefficients (map CC)
between two maps: map_1=Fmodel map and map_2=2mFo-DFmodel, where Fmodel
= k_total * (Fcalc + Fbulk), and 2mFo-DFmodel is what's called sigmaa
map. These maps are calculated using the model from input PDB file, and
reflection data (Fobs or Iobs) and R-free-flags from input reflection file.
You can define map_1 and map_2.
Depending on data resolution, the map CC will be reported per individual
atom or per entire residue.

But I am not sure that the map used here was the SA composite omit map. Will phenix use the omit map I provided or will it just simply calculate a sigmaA weighted 2Fo-Fc map based on the pdb?
