[gmx-users] clarification of equation 4.65

[Christopher Neale]

Dear Users:

can anybody confirm that there is a mistake in equation 4.65 on page 82 of the manual for version 4.6.1?

Specifically, I think that the final term should be C4*(1-cos(4*theta)) and not C4*(1+cos(4*theta)) where the difference is the sign of the cosine term ?

Thank you,
Chris.
