The vdw.pdf file shows the relationships between sigma and r0. If notation
is consistent, r0 = 2^(1/6)*sigma. So if the stotes parameters list a sigma
and an epsilon, I'd use the epsilon as-is (converted to kcal/mol if it's not
already there) and adjust the sigma according to the above equation, with
the result in Angstrom. But again, the paper should probably be explicit
about which parameters in whatever equation they are talking about.
Good luck!
