      - fixed a bug in the binning of the low-gain events, affected 
        the relative times in case of high-gain saturation.
+
+   * msignal/MExtractTimeAndCharge.[h,cc]
+     - fix the range for the low-gain extraction dynamically by 
+       using the calculated time of the high-gain extraction. This 
+       should solve the problem reported by Nuria for the extractors
+       deriving from this class.
