Detailed Description

The SimpePedestalCalculatorProcessor calculates the pedestal for each channel from all events in the run.

It just sums up all measured ADC values and calculates the mean value, so the data must not contain peaks. You need dedicated pedestal runs to record these data. The output is a simple lcio file with only one event containing the conditions data. Data base files or MySQL conditions data will not be supported.

Processor Parameters:

Parameters

InputCollectionName	Name of the TrackerRawData input collection (default: TPCRawData)"
OutputCollectionName	Name of the output collection (default: TPCPedestals)
OutputFileName	Name of the lcio output file (existing file will be overwritten). Default: TPCPedestals.slcio
