Hello,
I’m working with a TH2 histogram where the z-axis represents the dose at various depths. When I perform a ProjectionX(), I end up with the cumulative sum of all events along the z-axis. However, I only need the dose measured at the surface—i.e. I want to fix the z-axis to a particular value and avoid summing over it.
Has anyone encountered a similar issue? Would applying a cut on the z-axis before projecting or using ProfileX() be a better approach to isolate the surface dose? Any guidance or suggestions would be greatly appreciated!
