[phenixbb] How the sharpening were performed in PHENIX.

Hi, I was trying to do a B-factor sharpening using phenix GUI CreatMaps utilities. The output for the sharpened maps contains 2FOFCWT and PHI2FOFCWT columes, so I think they are sigmaA weighted 2Fo-Fc maps. But from Brunger's paper, the sharpening coefficients seems directly applied on Fo, and I wonder what happened before we get the 2mFoDFc maps. Or, the sharpening coefficients have been applied to the 2mFoDFc maps? Thanks for any information! Hailiang
