Hi guys,<br>
<br>
I've just made these plots, I'd like a comment. I plotted the
invariant mass for both my MCevents and data. I used the pairs that
are in the targetconstrainedV0candidates (stil don't know how it is
filled)<br>
requiring:<br>
1)that they had gbl tracks (trackType >=32)<br>
2)positron and electron energy >0.05 GeV<br>
3) (positron + electron energy) > 0.8*1.05<br>
<br>
This is MC data:<br>

<br>
this is real data (1 file of run 5772 pass2)<br>
<br>
<img src="cid:part2.09050208.07030306@roma2.infn.it" alt=""><br>
this is the overlap (normalized to maximum bin content):<br>
<br>
<img src="cid:part3.06050609.08070805@roma2.infn.it" alt=""><br>
<br>
this is an overlap with DATA shifed of 4 bins (8 MeV)<br>
<br>

<br>
I still have to do it using MDGRAPH data, work in progress.<br>
<br>
Any comment is wellcome<br>
<br>
