    * manalysis/MExtractSignal2.[h,cc]
      - removed uncommented code (arrival time)
+
+   * manalysis/MHPedestalPixel.[h,cc]
+     - is now filled with total pedestals (not per slice), but results are 
+       renormalized to values per slice (this is not to screw up with the 
+       pedestal RMS and the derived uncertainties)
+     - new function Renorm(nslices)
