 // This class implements several function useful to fit pt spectra,
 // including but not limited to blast wave models.
 //
-// It can return the same functional for as a function of different
-// variables: dNdpt vs pt, 1/pt dNdpt vs pt, 1/mt dNdmt vs mt. 
-//
-// Before getting the function you need, you have to chose the
-// variable you want to use calling AliBWFunc::SetVarType with one of
-// the elements of the VarType_t enum.
