Track selection

Tracks belong from "good vertices", according to BDT file provided by Valerio. Good vertices are identified by ** (1 - bdtvalue)/ntracks < 0.05**

1. 2 <= Nseg <= 28 (no fully penetrating tracks)

2. -150 mrad < tx,ty < 150 mrad

3. Track must have a segment in the last emulsion layer

4. Additionally, the initial angles are shifted (to center the beam at 0) by tx = tx0 - 4.64 mrad, ty = ty0 + 2.15 mrad
