Hi @singhra1994 I still didn't look into the helper functions, but I already spotted several issues in the logic of the filter itself. Please implement the suggestions, and then I will take a look at the helper functions as well.

Hi @singhra1994, thanks for addressing my comments! The code looks correct to me now, but I would like to ask @mfaggin also to check that I didn't overlook any other bug that might affect the SigmaC-K triggers.
Please also address my remaining comments and then as discussed in the trigger meeting, verify that the output of the task is identical for the other triggers before and after your changes, so that we can then merge it. Thanks!

I agree with this comment: leave your BDT fully independent from the others which are general for the triggers.

Hi @fgrosa @singhra1994 I tried to go through the modifications and I posted some comments. It looks to me that the already existing trigger Sc-K is not affected by the proposed modifications, but I have a couple of warnings/comments for the Sc-p part.

Updated PID cuts and added new parameters for SigmaC-pr correlation. Adjusted track selection criteria and improved comments for clarity.

Move this cut as suggested in the previous round of review
Updated configurable parameters for SigmaCPr trigger and added logic for SigmaC-proton correlation. Enhanced event tagging and BDT score handling for SigmaC candidates.

I have modified the block trigger SigmaCPPK in such a way that both SigmaCPPK and SigmaCP can be filled in the same block
