CAM4 vs CAM5 ?

Dear all,
I want to know that, in the compset F, F_2000 is to turn CAM4 on, and F_2000_CAM5 is to turn CAM5 on, is it true ? Or their differences only the phisical package?
Thanks very much.

CSEG and Liaisons
Correct. The compsets that don't explicitly contain CAM5 in the name are set up to use the cam4 physics package. That is implemented by providing the argument "-phys cam4" to CAM's configure utility. Compsets that contain CAM5 use the cam5 physics package, and that is implemented by supplying the argument "-phys cam5" to CAM's configure. The dynamical core is unaffected by the choice of the physics package.
