In the section of the user guide on the Arrhenius rate activation, the d{p} term multiplies the "Low" terms. In the .C file, the d{p} term multiplies the "High" terms, which I think is correct, so this is not so much a bug as a typo in the user guide. (Tripped me up though because I set it to zero!)
