Oussama3030 · 2026-06-18T13:18:34Z

Changes:

Added the file k892hadronphotonBkg.cxx , which is used to calculate the correlated background for the invariant mass spectrum in k892hadronphoton.cxx .
Minor MC related fixes in k892hadronphoton.cxx
Put the axis in sigma0builder.cxx in a configurable group.

@romainschotter @dmallick2 You are not supposed to approve PRs which introduce new errors or warnings.

@vkucera Thanks for checking. I have approved the request as suggested by the analyzer, which will take care of these next PR.
I would like to kindly ask @Oussama3030 to fix these errors in the next PR or in future submissions, as we need to mitigate them; otherwise, they may be ignored. I agree with Vit’s remark.
