#46 closed Bug (fixed)
Isolation routine mistakenly rejects tracks inside isolation cone

Description
In RESOLution::Isolation (src/SmearUtil.cc:1429), the algorithm rejects tracks that are inside the isolation code but happen to not be the closest neighbor track. This saves a bit of time in finding the closest neighbor track, but badly miscalculates ptiso .
The fix for this is to comment out Line 1440; I am attaching a patch that does this.

BTW, the credit for this fix should go to my colleague at IPMU, Biplob Bhattacherjee

Hi,
Thanks for the report, after some thinking I agree with you that we should only exclude the particle track and no other tracks in the cone. I will merge this patch into the next minor release.
