/**
 * @class AliHLTTPCCalibPedestalComponent
 * 
 * This class is the calibration component for the AliTPCCalibPedestal class 
 * used for pedestal calibration of the TPC. 
 * 
 * It inherits from the AliHLTCalibrationProcessor and uses the high-level 
 * interface. The output is the class AliTPCCalibPedestal as a TObject.
 *
 * The component has the following component arguments:
 *   -rcuformat <old/new>  : Wether to use old or new rcuformat ( default is new )
 *   -enableanalysis       : Wether to enable analyis before shipping data to FXS
 *
 * @ingroup alihlt_tpc_components
