+// ABSOLUTE CLEANING
+// =================
+// This method takes signal height (photons) times area ratio
+// ad the cleaning levels.
+//
+// The cleaning now is done in these levels (eg. 16, 20)
+// The meaning of the cleaning levels is essentially the same (the same cleaning
+// algorithm is used) but the cleaning is not done in different 'units'
+//
+// Example:
+//
+// MImgCleanStd clean(20, 16);
+// clean.SetMethod(MImgCleanStd::kAbsolulte);
+//
+//
 // Member Function:  SetMethod()
