Merging Histograms with different names

Hi,

I dont know if I am missing something obvious, but this is what I have.

hist1.root with just one histogram in it, named hist1 hist2.root with just one histogram in it, named hist2 Neither have any directory structure.

I somehow want hist1 and hist2 merged. Now when I try the usual hadd.C, it just gives me back whichever I put in first, hist1 or hist2, not the combined one.
And I cant certainly do hist1->Add(hist2); since that does not care for the relative weights, which are much different - otherwise I could have just did that and divided by 2.

Can it be done?

Thanks a lot,
Deepak
