+   * macros/starmcstereo.C
+     - changed filters to divide data between train and test sample for
+       gamma hadron separation studies. Now we use the modulus operator
+       applied to (Corsika) event number:
+         MF filter1("{MMcEvt;1.fEvtNumber%2}<1");
+         MF filter2("{MMcEvt;1.fEvtNumber%2}>0");
