AMBER Archive (2004)Subject: AMBER: gaff "ha" atom type

Dear All,
I am using antechamber as part of amber8 for the preparation of a
protein ligand for my simulations.
Antechamber assigns the type "ha" to a hydrogen at an aliphatic sp2
carbon (type "c2"), which is connected only to other carbons.
Is the type "ha" correct for such a hydrogen?
From the manuscript on the gaff force field I would expect such a
hydrogen to have the type "hc"?
Thanks very much,
Oliver
