21 | // | |
e9c06036 | 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. | |
