I do not think this is the only paper available for such a molecule in
this field... & for each structure one can find various charge sets.

For instance, the comparison of
is quite informative - if one is interested in charge values. I do not
think such differences has something to do with ... numerical errors.

This is why we have decided to adopt a global strategy highly similar
to that found in "Cieplak et al. J.Comput.Chem. 1995, 16, 1357" for a
large list of co-factors. The data will be available in R.E.DD.B. with
not only the FF libraries but with all the computational conditions so
that every user will be able to reproduce & even
critize/modify/compare what we have done.
