+\section  evaluation_s1 How to process invariant mass spectra for J/psi or Upsilon
+
+The macro MUONmassPlot_ESD.C reads back the MUON ESD informations and compute 
+the invariant mass spectra and corresponding uncorelated background. 
+Moreover gives the number of event in the resonance peak and the number of triggers.

-\section evaluation_s3 Macro MUONCheckDI.C
-
-MUONCheckDI.C performs a consistency check on the methods of the 
-AliMUONMCDataInterface and AliMUONDataInterface classes. There are several 
-helper methods in these classes which make it easier to fetch data, which 
-means there are at least two ways of fetching the data within the same class 
-interface. The macro checks to see that the results given by these different 
-methods are identical, as they should be.
-
-The macro also inherently exercises the AliMUONMCDataInterface and 
-AliMUONDataInterface classes and should be run after any modifications to 
-these classes to see if things still work. Putting it another way: 
-MUONCheckDI.C is a testing facility for developers of these two classes.
+This chapter is defined in the READMEevaluation.txt file.
