Subject: Proton barrier heights in PM3

A referee for a paper I submitted states that "PM3 is well-known to
overestimate proton barrier heights".  He/she may be right (although   
this has no effect on the conclusions in the paper), but in any case
I need to find a specific reference which addresses this "well-known"
fact.  I would appreciate it if someone could point me to such a 
reference.

Thank you.
