Continuing tuning of MinuitVF for 7.7GeV production, the following are (Vx vs Vz) and (Vy vs Vz) within the TPC.

The next six plots are Vx vs Vz (X vertex position versus Z vertex position).

Below is R = 1.5cm, DCA = 3cm, Min # of Tracks = 5 -- the default settings.

Below is R = 1.5cm, DCA = 6cm, Min # of Tracks = 2
