Hi @hanseopark ,
Thanks for making these changes, the code looks good to me. Although there are some limitations with your method, it only allows for either 2 or 3 prong SV reconstruction. If you want both, you can't use this method, instead you will have to activate the 2prong and 3prong functions. But for tagging the old limitation is still there, you can only tag either 2 or 3 prong SV you can't use both. But this is not a big problem. I think the code can approved the way it is.

This is the issue I was worried about.
In my opinion, performing a side-by-side comparison using tags will ultimately be difficult.
