Re: [ccp4bb] Definition of Fourier coefficients

[Engin Ozkan]

I remember cuting and pasting on my little board in my cubicle Table I 
from Randy Read, Acta Cryst (1986), when I was a graduate student 
wondering about sigmaA. It is a table of definitions of terms and 
formulas, and helps one conceptually understand the terminology. It is 
from before the days of free R-statistics, so you may not be able to 
find in there how they are calculated these days, but it is still a good 
reference.

Hi,
 
What do m and D indicate in the Fourier coefficients for a 2mFo-DFc map?

I've dug a bit in web and CCP4 doc  but not found an explanation, though I'm 
sure its there.

Thanks,
