SFO Populations
***************

In the section that prints the SFO populations of (selected) MOs you
may occasionally find *negative* SFO contributions for some SFOs in
some MOs. This may seem unphysical and hence suspicious, but it is
only a result of the Mulliken-type analysis method that underlies the
computation of the SFO contributions. See the section below that
discusses the output file. The same holds for contributions larger
than 100%: these numbers may be correct (mathematically, given the
Mulliken population formulas).
