Read TH2D from file

ROOT
1

Dear all,
I try to get the bins’ content of a TH2D (48x48 bins) that I saved in a root file.
The histogram is read, since I can visualize it through the macro, but I get for every bin, a 0 content.
Attached is my macro.

Could you please give me any advice? Thanks!

Post your “TH2D.root” root file here.
