<p>The test only contained what was in that file, so no background.</p>
<p>I can do it with background, but there is currently an open issue with the v3-fieldmap exclusive to beam-tri that I cannot find the source of: </p>

<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>
<blockquote type="cite">
<div class="">Also, does the MC sample include full beam background, or is this only the tridents?</div>

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="">

<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="">

Cheers<br class="">
