Calibration Variables
One of the important parts of the calorimeter running is the online calibration (CAL CALIB) of the detector as well as its associated electronics. This software will be responsible for obtaining the necessary information required to calibrate the D0 Calorimeter during Run II. It is a primary tool for detecting electronic failures. These failures can affect the channel to channel response of the calorimeter and can affect the trigger rates. The primary task of CAL CALIB is to accumulate beam off data with a random trigger for each calorimeter channel and then to calculate their mean, sigma, third moment, and fourth moment for both pedestal and pulser runs. Determination of calorimeter bad channels requires both pedestal and pulser data. A variety of fits are required to be performed by CALIB when determining its definition of bad channels.
