Hi @mstahl, @tpajero, @fsouzade, @lpica, @roneil, I made quite a few updated to the lc_to_phh module, mainly introduced maximum to IPCHI2 to Lc+ candidates and decreasing IPCHI2 of daughters to 6. Those cuts are mainly based on Run 2 selection, previously I had much larger displacement of daughters and I think it would kill too much of prompt signal. With these cuts rates of all lines decreased, new rates added to the table.

Please let me know if you are OK with those changes.
