Hi, Vitaliy!

Besides the ntuple, there are two other solutions in place: one is Chi's
DST (have you tried it yet?), the other one is my mini-DST I wrote just
for e-p purposes, but it could easily be extended for other channels (it
only needs target state information for deuterium, which I did not bother
with - the particles are booked dynamically, in an expandable TClonesArray
that grows as needed by the number of tracks - it books duplicate tracks
too, of course - in that particular event). The whole structure is a TTree...
The part of code that does this in lrn (Chi integrated my code about two
months ago) is under a comment containing the word "ep_skim")...

If for some reason you cannot use Chi's DST, please feel free to modify
the "ep_skim" thing to include deuterium target spin info as needed.
I think it would solve your problem, it was for the purposes you mentioned
that I wrote it... and I tried to keep it very simple, so it would be very
easy to use for analysis.

Cheers,
Adrian
