      - fixed the NaN-problem in the calculation of Alpha. More 
        information can be found in the comments there.
+
+   * mhist/MHFadcCam.cc:
+     - skip MC events which have no FADC information stored
+     - better output in case of changes in the number of slices
+     
+   * mhist/MHFadcPix.cc:
+     - fixed the missing y-axis (UseCurrentStyle()) 
+
+   * mmain/MDataCheck.cc
+     - added 'Time Spectra of Cosmics' button
