+// If wished there is the possibility to calculate for each channel and time bin
+// the mean pedestal [pedestals(t)]. This is done by
+//
+// 1) setting SetTimeAnalysis(kTRUE),
+// 2) processing the data by looping over the events using ProcessEvent(..)
+// 3) calling the Analyse() and AnalyseTime(nevents) functions (providing nevents)
+// 4) getting the pedestals(t) using TArrayF **timePed = calibPedestal.GetTimePedestals();
+// 5) looking at values using timePed[row][pad].At(timebin)
+//
+// This functionality is intended to be used on an LDC bu the detector algorithm
+// (TPCPEDESTALda) to generate a data set used for configuration of the pattern
+// memory for baseline subtraction in the ALTROs. Later the information should also
+// be stored as reference data.
