Hi,

This is because the HepTuple software assigns a default value for the
branch ( "_1", "_2", etc.) when you do not specify one.

In order to change it just do 

 _ntuple->column("PMsBranch::PMsCut",phi_cand_mass);

Philippe.

Hi,
   Using HepNtuple, when I create an ntuple column with a command like:

 _ntuple->column("PMsCut",phi_cand_mass);

When I look at the resulting root file the leaf is called "_1" and not
"PMsCut" .. any idea why?

(using version v2_26_00g with KCC_4_0)

cheers

Mat
