// 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.
