1 ColumnWise_Ntuples

  ColumnWise Ntuples (CWN) are now (version 4.03) supported in
  Mn_Fit. In addition to treating them like single variable ntuples
  you can also specify a range of elements or an array element that
  should be accessed.

  The number of columns you give for a CWN variable should always be
  the same as its definition. Use `:' to give a range of variables. If
  you want to give a range of more than 1 variable, it is up to you to
  make sure that the ranges are consistent:

  ntuple project 34 rval2(2:nval2)*rval3(1,2:nval2) rval3(4,2:nval2) -
   &11 75 -5 10 75 -5 10

  Note that the limits of each variable of a CWN are not
  known. Therefore you always have to give the limits for plotting
  yourself.

  CWN variables that you want to access in a COMIS function as part of
  an `NTUPLE PROJECT' command have to be specified using the
  `SET NTUPLE VARIABLE' command.
  However, for the `NTUPLE SCAN' command all variables will be fetched.

  WARNING: If you try to loop over a `CUT' variable this will not be
  checked, but the loop will be ignored. If you need a cut variable to
  change with the element number of a CWN, then you will have to use a
  COMIS function for the cut.
