+     - Condition to assume a constant background in the fit 
+       of the ON and OFF data is softened: 
+          1) Bins with zero content are allowed (if they are less than 10%
+          of the total number of bins used). Yet their error is set to 
+          a huge number 10E19; which means that they are not taken into account 
+          in the fit.
+          2) Maximum number of bins with low content (less than 9) is increased 
+          from 5% to 20%. The error of these bins is set to 3.
+
+       The motivation of these changes is to allow the fitting procedures also 
+       in those cases where the background rejection is that large that very few 
+       events remain in the background region of the alpha plot. This situation 
+       is occuring quite often when using the Random Forest and SPECIALLY, when 
+       making large SIZE cuts.
