Hi Suzanne,
The TTree::Draw option "prof" is more than just a drawing option.
It generates a TProfile instead of a TH2F.
Note also that you can specify "prof" or "profs"
"profs" generates a TProfile with error on the spread
"prof" generates a TProfile with error on the mean
see TProfile.

There is no point in drawing a TH2F with the prof option.
