Detailed Description

Framework module that produces a collection of calo towers in the region of interest for Tau HLT reconnstruction, depending on tau type trigger: Tau1 - take location of 1st L1 Tau Tau2 - take location of 2nd L1 Tau; if does not exists, take location of 1st Calo Tower ETau - take L1 Tau candidate which is not collinear to HLT (or L1) electron candidate.
