ticular care is required to compute BSSE by the counter-poise
method for the DFT module. In order to include terms deriving from
the numerical grid used in the XC integration, the user must label
the ghost atoms not just <TT>bq</TT>, but <TT>bq</TT> followed by the given
atomic symbol. For example, the first component needed to compute the
BSSE for the water dimer, should be written as follows
