Dear Yavar,

you are going to miss the contribution of the augmentation charge to the 
|psi|^2. That is not important if you are interested in spacial regions 
far from any atom (small or zero overlap with the augmentation spheres); 
that might instead be important if you want a quantitative analysis in 
the atomic region. For the latter, however, the analysis of the 
atom-projected DOS could be much more useful (or you could implement 
augmentation charge contributions).

PS please write to the list only, not to personal addresses.

Guido
