Entry number 260914

This entry is a followup to: 260824

I looked at the offline DT from BBNormaAna more closely. Earlier (halog 260824) I was not replaying enough events(only 50k), so the DT was completely different than what we see online. If we replay more than 100k events then we get correct DT from offline analysis.

It is good idea to setup a replay script to analyze all the events looking only at the normalization and scaler stuff, it will be very quick.

Run 1382 :

------------ BBNormAna Trigger Summary   ---------------- 
Trigger      Prescale      Num evt        Num in        Livetime
---           Factor       CODA file      Scalers
