Merge pt hard bins for jet-jet MC in PWG-JE

I run jj MC for 20 different pt hard bins and obtained 20 root files. I am wondering if someone can point where I can get a script to merge the different pt hard and get the pt cross section.

Dear Haidar,

You can merge the 20 ROOT files with the hadd tool, available together to the root command.
The interpretation of the result depends on your physics case and is beyond ROOT scope.

Hi Ganis,
Thanks for the reply. I know of hadd command but what I am looking for is how to produce a plot like the one I attached herein.rootforum
