19 @brief Derived class for the pedestal detector algorithm.
20*/
21//
22// This class implements the virtual functions of the AliFMDBaseDA
23// class. The most important of these functions, FillChannels(..) and
24// Analyse(...) collect and analyse the data of each channel. The
25// resulting pedestal and noise values are written to a comma
26// separated values (csv) file on the go. The csv files produced in
27// this way are the basic input to the AliFMDPreprocessor.
