DST Ntuples

Modification logs.
Sep.20,1999
The first version. Only ADC values are calibrated.
Ntuples files which contain calibrated variables are located under 
    /t912/dst/
Their contents are explained here.

Ntuple ID

Various vaiables are stored into separate Ntuple ID's

Ntuple Variables

For run summaries
their variables are equivalent to those in raw data ntuples. Please refer to a previous page for data ntuples.
For events:
All calibrated and pedestal-subtracted data has a charcter, "c" at the beginning of variable names.
