You don't even have to do do any programming.  Just use xmgrace that can 
integrate your d-DOS curve.

ed=\int End(E)dE /\int nd(E)dE

You can also get the mean width of the d-DOS etc...

Wd=\int (E-Ed)^2nd(E)dE

You just compute the DOS projected on the relevant d orbital, and than compute 
it first moment ? SB

Hi everyone
I am posting this question for someone to help.
