@bhattdurgesh921-sys . Please make PR title clear what changes were made that can be followed up. Regarding spin alignment studies for L(1520) , there were already a code prepared for the same (https://github.com/AliceO2Group/O2Physics/blob/master/PWGLF/Tasks/Resonances/lambda1520pbpb.cxx) . if you want to made your own same thing with additional new task according to your convenient task but mention it in clear way in PR, adding a new task there is no issue as several analysis task already available for same analysis . Run 3 analysis, we are not strictly following adding analysis task structure or maintenance as it is approved by several people. I would request please add the PR title and changes so that people can follow and conflict will not arise in future among the analyzer we faced the same situation in past.
