Calibration: CAL Pedestals
ID: C18 in LAT-MD-00446-04
Description: Pedestals correspond to an ADC output for zero input to front-end electronics (FEE). There is a pedestal value per energy range of each crystal face. Each pedestal is characterized by a centroid and a width of a distribution of a given (TBD) number of triggers. Since there are two diodes in each of the two crystal faces, we will have eight pedestal distributions per crystal. A combination of Tower, Column and Layer uniquely identifies a crystal, so crystal numbers vary from 0 to 95 and should also be present in the database.
Software required: SAS
