Can anyone tell me how to do the following. It should be easy but running into some problems
I have a root file which has the following structure.
Calibrations.root (file)----
|
Calx (Tree) ------
|
E1 (Branch)
‘Energy’
'Bins’
E2 (Branch)
‘Energy’
‘Bins’
etc…
So you can see that within each branch of the tree I have two leafs corresponding to energy and bin number. How do I place some float number into either ‘Energy’ or ‘Bins’.
Thanks for you help in advance.
Nick.
