 //
 // Class AliRsnHistoDef
 //
-// Definition for a histogram type.
-// Since one could do an analysis which is not an invariant mass
-// the histogram definition should be more flexible, and it is stored
-// separately in a new class.
-// This class considers the possibility of a 1D or 2D histograms
-// with its related binning, and can create a new histo from his definitions
+// Histogram definition.
+// Contains required informations to create a histogram
+// with fixed bin size: number of bins, minimum and maximum.
+// Variable bin sizes are not considered because they are 
+// not used as typical output of analysis in this package.
