Matching Data

I have to match histograms that I have from a simulation I made with real world data, that is see if the simulation data is a good fit with the real world data from the detector, and I am trying to do this with PyRoot. I am told that I should look at the TTree, TH3, and TBrowser to do this, and I was wondering if you would recommend that I do this.


if you have histograms already, I would exclude the TTree.
If the histograms are many, TBrowser is probably not the best way to approach the task.
TH3 is a 3-dimensional histogram, if this type of histogram is present in your set, yes, you’ll be using it.
