+//  ReInit before the first event from the drive-tree is read (because
+//  the first data event may have a time-stamp later than the first
+//  drive event) we always assume that the current run is a data run.
+//  If the assumption is true fReport should be initialized correctly.
+//  For MC runs this should never happen, Because they are read though
+//  MReadMarsFile which gurantees, that ReInit is always called before
+//  Process. If we encounter such a case we stop execution.
 //
 // Future: Interpolate the pointing position for each event between two
