pair_style sw

Dear LAMMPS users,

I am currently trying to understand the Stillinger-Weber
implementation in lammps, however, I believe I may be missing
something.

Are the epsilon and sigma parameters in pair_style sw analogous to
those in pair_style lj/cut, if not, could someone shed some light?

I'm currently commenting the source as I'm trying to implement a
similar three-body potential, but I'm still not getting what these two
parameters are specifically for.

Thanks in advance,
Alejandro

The pair style sw doc page gives the formula for the SW interactions
and it has the sigma and epsilon values in it. You can see
from the functional form that they are similar to the sigma/epsilon
in the LJ formula, but different.
