Re: [phenixbb] difference density map

Hello,

Hi, My favorite explanation for why differences show at full height in a 2Fo-Fc map is that the map is really a Fc + 2(Fo-Fc) map.

I'm sure there is a paper in Acta Cryst from the 1950's that gives the definitive derivation

Dale, I thinig an appropriate paper may be P.Main, 1979, Acta Cryst, A35, 779-785 and multiple references therein (say, Luzzati, 1953; etc). Best regards, Sacha
