     @brief   Derived class for the pulse gain detector algorithm.
 */
-// This class contains the implementation of the gain detector algorithms (DA) for the FMD.
-// The data is collected in histograms that are reset for each pulse length after the 
-// mean and standard deviation are put into a TGraphErrors object. After a certain number of pulses
-// (usually 8) the graph is fitted to a straight line. The gain is then slope of this line as
-// it combines the known pulse and the response of the detector.
