Meeting No8 - Doug's DB

This week I checked what kind of results I get with Doug's old database. I compared the results of this check with the results of the previous analysis. I also made the same comparison for the 360MeV Ledex data:

Threshold Pi0 data:

Ledex data:

From the results we can see, that the two DB for the Ledex agree well, while there is a big discrepancy between Doug's database and Mitra's best DB.

Discussion:

1.) Error bars on energy plot shown last week
2.) Cuts for Mitra:

    a.)  (((int)DL_evtypebits& 1<<5) ==1<<5)
    b.)  ((int)L_tr_n==1)
    c.)  ((int)BB_tr_n==1)
    d.)  missing_mass_sq_B>=0.0
    e.)  Various cuts on coincidence time

3.) It will be necessery to re-check code, due to the DB issues.
