In my case it was clear, because the person who generated the PS told me that
the NLCC is in the form 4*pi*r^2*charge, but I don't know if this is in general
like this, because I guess there exist also other programs which can calculate
som NLCC for a given potential. As soon as I know more about the NLCC from the
fhi-code I will tell you.

Greetings,
