@brief Derived class for the pedestal detector algorithm.

//
-// This class implements the virtual functions of the AliFMDBaseDA class.
-// The most important of these functions, FillChannels(..) and Analyse(...) collect
-// and analyse the data of each channel. The resulting pedestal and noise values are
-// written to a comma separated values (csv) file on the go. The csv files produced
-// in this way are the basic input to the AliFMDPreprocessor.
