TNtuple
A simple tree restricted to a list of float variables only.
Each variable goes to a separate branch.
A Ntuple is created via
TNtuple(name,title,varlist,bufsize)
It is filled via:
TNtuple::Fill(*x) or
TNtuple::Fill(v1,v2,v3.....)
TNtuple(): TTree()
*-*-*-*-*-*Default constructor for Ntuple*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-* ==============================
TNtuple(const Text_t *name, const Text_t *title, const Text_t *varlist, Int_t bufsize)
:TTree(name,title)
*-*-*-*-*-*-*-*-*-*-*-*-*Create an Ntuple*-*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-* ================
The parameter varlist describes the list of the ntuple variables
separated by a colon:
example: "x:y:z:energy"
For each variable in the list a separate branch is created.
Use TTree to create branches with variables of different data types.
