    I Eun-Joo,
    I just wondered where the numbers were kept.  I have seen several "DVM"
    runs, but no mention of what the V_drift is, and I could not find it from
    home.  I thought that maybe these were kept in the same way as the magnet
    monitor data, which is wrong.
    Do you (or does anyone else?) know if the drift velocities in the data base
    are 'up to date?'
    Thanks,
    Ian

    Dear Ian,
    
    What's "the store" means?
    As I know, the input of drift velocity is in the DetectorParameters.txt,
    if you don't use the value from DB.
    (tpcModule->SetUseDriftVelocity(kFALSE);)
    Once we finished the drift velocity calibration, the values go to DB, and
    we can use it. Now TPM1, TPM2 dv set a bit high in
    theDetectorParameters_ejk.txt.
    (0.195, 0.18)  Thanks....
