<div dir="ltr">Dear all
<div><br>
</div>
<div>I took a look at Evgeny's events and uploaded some information on the docDB</div>
<div><a href="https://clas12-docdb.jlab.org/cgi-bin/DocDB/private/ShowDocument?docid=502">https://clas12-docdb.jlab.org/cgi-bin/DocDB/private/ShowDocument?docid=502</a><br>
</div>

</div>
<div>I was not able to produce CED pictures because the input DSTs from the trains do not have detector banks</div>
<div>However I think we can still see three kinds of events</div>
<div>(1) CVT "ghost" tracks around polar angle = 90 degrees (5% of events)</div>
<div>(2) CVT duplicate tracks correlated with the proton (22.5% of events)</div>
<div>(3) accidental tracks (72.5% of events)</div>
<div><br>
</div>
<div>Some samples of 1k events from each category are available under</div>
/work/clas12/fxgirod/Evgeny/</div>
<div dir="ltr">In principle we can filter these events from decoded files, reconstruct them specifically and look at them on CED <br>
<div><br>

<div>Please let me know if you have questions of suggestions</div>
