      - take fNameWeightsFile into the streamer, otherwise the Clone() 
        will always create an extractor with cosmic's weights. 
+     - set fOffsetLoGain to a slighly higher value. The DF seems to 
+       have a different offset since it uses different pulse shapes 
+       and thus sightly different time definitions.
