+    * library/MImageParDisp.[cc,h]
+     - Container for the estimated distance to source position DISP.
+    * library/MDisp.[cc,h]
+     - Container holding the parameters used for the DISP expression.
+       The current DISP parameterization is defined in MDisp::Calc.
+    * library/MDispCalc.[cc,h]
+     - Task calculating DISP with the expression and parameter values
+       stored in MDisp. Training and test matrix of variables to be 
+       used in the DISP optimization are also defined within 
+       MDispCalc::InitMapping.
+    * library/MHDisp.[cc,h]
+     - Container for the histograms to judge the quality of the DISP 
+       estimate. MHDisp::GetChi2 returns the value of the quantity 
+       requested to be minimized by Minuit, which is defined and 
+       computed in MHDisp::Fill and MHDisp::Finalize. 
+       MHDisp::GetSkymapXY returns the reconstructed map of source 
+       positions. MHDisp::SetSelectedPos function to choose the 
+       selection method of the DISP source position solution.
+    * library/MFDisp.[cc,h]
+     - Filter to select a sample of events to do the DISP optimization.
+       Use MFDisp::SetCuts function.
+    * library/MFindDisp.[cc,h]
+     - Main class for DISP optimization:
+        ::DefineTrainMatrix, ::DefineTestMatrix, ::DefineTrainTestMatrix
+       generate the training and test samples (in the form of matrices)
+       from the input file.
+	::FindParams is the function steering the optimization (over the
+       training sample), calling Minuit, passing the fcn function to be 
+       minimize and defining the event loop to be executed in each step.
+	::TestParams tests the quality of the DISP estimate using the 
+       test matrix sample
+    * library/Makefile, library/IFAELinkDef.h
+     - include Disp classes.
