5  * InvariantMassThreeTOBsIncl1.cxx
6  * Created by Carlos Moreno based on InvariantMassInclusive1 by V Sorin
7  *
8  * For questions contact atlas-trig-l1topo-algcom@cern.ch.
9  * @brief algorithm calculates the sqr of the INVMASS of three TOBs from one list and applies invmass criteria
10  *
11  * @param NumberLeading
12  *
13  * First version assuming same cuts in all TOBs. If we'd like to have a version similar to *INVM*-MU4ab-MU6ab-MU10ab
14  * we'll need to change the following:
15  * p_NumberLeading* will need to be added to account for the different lists. This could help to have something like *INVM*-2MU4ab-MU6ab
16  * MinET2,3 will need to be added to apply the different cuts on the lists
