To have DS tracks with full PID inc new hypothesis construction by 29 April.
Through going tracks matched with PID (not inc EMR)
- PID on DS tracks.
- PID on through tracks from Jan's supply of 9000.
- Adjusting efficiency to include errors - ongoing
- Correlated errors on efficiency & purity - ongoing
- Efficiency measurements using z position in tracker - ongoing
- Correlated errors for PID
