Small script to compute charge from a root file :

/adaqfs/home/adaq/e04018/onlana/GetCharge.C 

 ( this script has a bug it did not take into account the scaler offset ) I will put the updated values.

Additionnal data for BCM calibration : run 3893 and 3894 http://www.jlab.org/~adaq/halog/html/0705_archive/070530190919.html

Files are located on : /work/halla/e04018/disk2/bcm/


Scalers offsets from run 3893 

T->Draw("left_bcmu3cnt:left_clkcount/1024","abs(IBCxxxxCRCUR1)<1&&left_clkcount>250e3&&left_clkcount<400e3");
