[DFTB-Plus-User] question about transition weights in EXC.DAT files

[Mostafa Tavakoli]

Hi
Can anybody please tell me what are "weight"s reported in EXC.DAT files?. I
read the manual and the only thing found there was that weight=1 means we
have primarily transitions. I want to know the physical meaning of weights
and that what do weights smaller than 1 mean?
Thank you very much.
