Hi all,
some BAD news on the timestamp side.
Working hard on cutting the duplicates I've always assumed that among the
same mode (& superblock) there are not duplicated events.
Checking on the timestamp provided by CPFramework (but it was a very quick
check) I had validated this assumption.
Now the problem comes out again:
running on Dstar0 (and now I'm trying to check also the other seeds)
reduced entuples I found that in the SAME REDUCED ROOT FILE and NTUPLE
there are duplicated events.
The checked file is :
/u/ec/ursl/d/output/breco-112101/data/
dstar0_110901_superblock2_2000_b1-s2_aa.root (.hbook)
I have ran CPF and anaRecoil on this file and I got some duplicated
events:

It is really difficult to find those events because they are replicated in
the same order but in really different parts of the output files
(from the first to the second chunk I got ~5000 events....)
We really have to find out how this is possible.... Now we are using
ntuples that may contain duplicated SIGNAL events.
I'm going to quantify the problem and to check it among the various seeds
but I think that is a very hard work.
Does anybody has an idea on how this can happen?
Cheers,
Alessio
