Tuning of StMinuiVertexFinder, simulation (rcf1263) CuCu62 GeV, |z| < 10 cm

Tpc + Svt (hit errors : 80 mkm and 80 mkm, X and Z) + Ssd (30 mkm and 700 mkm, X and Z)

• Old vertex finder with wrong errors σ = 190 mkm;
• New vertex finder with DCA track errors σ = 75 mkm;
• Account correlations, Scale = 100 σ = 85 mkm, pull = 1.9
• Account correlations, Scale = 10 σ(X,Y) = 82 mkm, σZ = 92 mkm, pull = 1.35
• Account correlations, Scale = 5 σ(X,Y) = 89 mkm, σZ = 110 mkm, pull = 1.2; Set Scale = 5 as default.
