Dear Evangelia
for the moment the Sato coefficients are not implemented in Fluka, and
will not be implemented in the next release. We are considering the
possibility to implement them later on.
As for differences induced by the two sets, we have no experience, sorry.
Probably you can find general documentation (mean not relative to Fluka)
in literature.
Regards
Paola
