Dear codeowners,

Is it possible to overcome the "magic number" errors in the O2 linter / O2 linter (pull_request_target) check? In my opinion it would unnecessarily complicate the existing code. You can see an example of such a solution in the PWGLF/Tasks/GlobalEventProperties/flattenicityPikp.cxx file (lines 1814-1908)

The way to "overcome" it is to write it in a better way. From what I can see, you map some number to other numbers. So how about using a map or an array, for example?
