it does...</div>

Hi Luca,
<div class=""><br class="">
</div>
<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>
<div class=""><br class="">
</div>
<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>
<div class="">Also, does the MC sample include full beam background, or is this only the tridents?</div>
<div class=""><br class="">
</div>
<div class="">Cheers,</div>

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="">
<br class="">
<span id="cid:part1.05030906.01070903@roma2.infn.it" class=""><invmassLuca.png></span><br class="">
<br class="">
<br class="">
this is from run 5772:<br class="">
<br class="">
<span id="cid:part2.01000000.01050606@roma2.infn.it" class=""><invmassRun5772.png></span><br class="">
<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 class="">
<br class="">
Cheers<br class="">
