+/*
+
+Macro to prepare the necessary objects to perform spectrum unfolding
+(to be used by the class AliCFUnfolding)
+
+Note that the efficiency calculation (and therfore the container filling)
+has to be done using MC values (and not reconstructed values)
+
+This macro creates the following objects :
+- (AliCFContainer) container : used to calculate the efficiency (see AliCFEffGrid)
+- (THnSparseD) correlation : this is the response matrix
+
+Once you have run this macro, you may launch unfolding using
+the example macro CORRFW/test/testUnfolding.C
