are already 0.0 at their cutoff such as <I>lj/charmm/coul/charmm</I> are
not affected by this setting.

<P>The <I>mix</I> keyword affects how Lennard-Jones coefficients for epsilon
and sigma are generated for interactions between atoms of type I and
J, when I != J. Coefficients for I = J are set explicitly in the data
file or input script. The <A HREF = "pair_coeff.html">pair_coeff</A> command can be
used in the input script to specify epilon/sigma for a specific I != J
pairing, which overrides the setting of the <I>mix</I> keyword.

<P>These are the formulas used by the 3 <I>mix</I> options. In each case, the
LJ cutoff is mixed the same way as sigma. Note that some of these
