Hi all, I have added another module for Klong killing. It is called ListEffLundFilter and filters a candidate list and applies a flat killing for candidates with a given LUND id. The LUND id is taken from the best associated MC candidate. For Klong systematics we will use a 100% killing. There is some example code in VubXlnu.tcl. For the VubXlnu module you need set KlongKilling 1.0 for the 100% killing. The setup is in VubXlnuPhysics.tcl. It filters the neutral list for the recoil side. I have also added a module (KlongEnergyCorFilter) for applying an energy correction factor based on BAD1055. Before we use this we have to check if our neutral cuts, which are different from BAD1055, have an impact on the correction factors.
