neugen vs lipari

 "Ciao" all

It is very interesting, in my opinion, to have some files DST-like
from the
NEUGEN generator, as proposed by Nolty. I can copy the FZEX files
and produce them, if necessary.
However, some preliminary checks can be performed.
First, it seems to me not true that in the Lipari code the NC are
identically zero. In fact, ~5% of my UGS+ID events, and almost the
same
fraction in the IU (Surdo) sample were produced by NC.
Second, ~1 year ago Antonio find some bugs in the Lipari generator,
and
we use now the corrected code. One copy of the corrected CAR file with
the Lipari code is in:
AXPGS::DISK$MACRO:[SPURIO]INTERNAL.CAR
Third, all the data cards should be the same: this is the output for
our data card, assuming a neutrino threshold of 0.1 GeV.
In 79 year, we expect in MACRO:
79y * 5.31kton*(111.49+41.83) (kton year)**-1 = 64316 events
