Hi Luca,

<div class="">I am really glad that at least you are up and
running again with code. Probably should not update your trunk,
or at least preserve your current one, so it doesn’t get messed
up.</div>

Sure, I won't risk any udate!<br>

<div class="">Did you impose any additional cuts to your data
sample? It looks like you did not and so have a large amount of
extra background.</div>
</blockquote>
<br>
I didn't apply any cut, just read the collection and used the
.getMass() method.<br>
In the data I see what seems like an overlap of two distributions. I
need to know how the collection gets filled to understand something.
This is interesting, though.<br>

<div class="">Also, does the MC sample include full beam
background, or is this only the tridents?</div>
</blockquote>
I let Bradley handle the reconstruction, anyhow he run my data
through the same chain as the other MC, so it should contain
everything.

Hello guys,<br class="">
thanks to <u class=""><i class=""><b class=""><big
class="">Bradley</big></b></i></u> some of my
events have been reconstructed. I read them and plotted
the invariant mass using the
"TargetConstrainedV0Candidates" collection.<br class="">
I run the exact same driver over one file of run 5772
(pass2)<br class="">
these are the results: My InvMass:<br class="">

this is from run 5772:<br class="">

Real data looks wierd.<br class="">
<br class="">
I would like to know how the
"TargetConstrainedV0Candidates" collection gets filled,
I tried to look in the code but I got lost.<br class="">
<br class="">
today I can't attend the software meeting, maybe we can
discuss it tomorrow. Until then, any comment is welcome<br

Cheers<br class="">
