Following are QA plots (day-by-day basis) of some variables filled in D0Tree :

(up to now only for day 124 to day 150, I will add the others later)

Each pdf has a sumarry plot at the end

1. pointing resolution vs. 1/P (pdf)
2. z vertex distribution of events before and after cuts  (pdf)
3. rapidity distribution of D0 candidates (pdf)
4. inv. mass of D0 candidates at each steps (= cuts) (pdf)
