Detailed Description

Class for defining vetoes within the Dalitz plot.

Each veto is defined by an index corresponding to one of the three invariant mass-squared variables, and maximum and minimum values for the veto's range in the specified variable.

Each mass-squared variable is numbered according to the index of the daughter not involved in the vetoed mass-squared variable. For example a veto in m12 squared would receive the index 3.

Since v3r2, in the case of a symmetric DP, vetoes in m13 or m23 will automatically be symmetrised to the other variable (so only one needs to be specified). However, if one wants to veto a region from a symmetric DP in the already-symmetrised co-ordinates, the special indices 4 and 5 can be used that will apply the veto to mMin or mMax, respectively.
