Dear all,
I have a TH2 histogram representing a 2D efficiency map. I want to project this over one of the two axes and for this I plan to use TProfile. I want to select the bins to be “imported” in the TProfile object by skipping those who are empty.
I try to give some more details: the 2D efficiency map is for testbeam data of a pixel sensor. The beam spot was smaller than the sensor so there are bins never reached by any beam particle. I would consider those bins as empty and I don’t want to include them in the TProfile object. (Another case is represented by masked pixels, pixels which were not included in the data taking).
So, is there a way to identify empty bins please? I could select bins with content greater than 0 but I fear this could be seen as a bias in my analysis.
Many thanks in advance and best regards,
Marco Bomben
