1. Making new distotion maps:
+  static void  MakeDistortionMap(THnSparse * his0, TTreeSRedirector *pcstream, const char* hname, Int_t run,  Float_t refX, Int_t type);
+  static void  MakeDistortionMapCosmic(THnSparse * his0, TTreeSRedirector *pcstream, const char* hname, Int_t run,  Float_t refX, Int_t type);
+  static void  MakeDistortionMapSector(THnSparse * his0, TTreeSRedirector *pcstream, const char* hname, Int_t run, Int_t type);

2. Modifications for TPC-TPC matching in the MakeDistortionMap

3. Possibility to specify the weights in the composed correction.
