@ -161,10 +161,10 @@ thermostat. Because the random forces on different atoms are
independent, they do not sum exactly to zero. As a result, this fix
applies a small random force to the entire system, and the
center-of-mass of the system undergoes a slow random walk. If the
keyword <I>zerosum</I> is set to <I>yes</I>, the total random force is set
exactly to zero by subtracting off an equal part of it from each atom
in the group. As a result, the center-of-mass of a system with zero
initial momentum will not drift over time.
