5  * InvariantMassDeltaPhiSumEtInclusive1.cxx
6  * Based on implementation of InvariantMassDeltaPhiInclusive2. For questions contact atlas-trig-l1topo-algcom@cern.ch.
7  *
8  * @brief algorithm calculates the sqr of the INVMASS between all element of a list and applies invmass criteria.
9  * For pairs passing the INVMASS cut a further requirement based on DeltaPhi is applied, addressing ATR-19377
