<p>For clarity, it looks like tpass6 actually used 'hps-distribution-3.6-20160229.015546-43-bin.jar' not the '3.6 release', but the same run number problem happens for that jar as well.</p>

<p>Investigating further, this may be the problem:</p>
<p><br>
</p>
<p>Apparently, the most recent jar (3.6 release) always sets the run number to '0', even when specifying it in the command with -Drun=5772.</p>
<p>All jars that were checked before the problematic 3.6.1 appear to assign the correct run number of 5772.<br>

<p>It should be checked if this also affects data reconstructed with 3.6, or only Monte Carlo. In any case, this would definitely be a thing to fix.<br>

<p>I know this was supposed to be the "final pass", <br>
</p>
<p>but it looks like there are far too few Moller events being readout in Pass 6 Monte Carlo.</p>
<p><br>
</p>
<p>Looking further into this, it is because the >3-hit clusters in Pass 6 are getting decimated BEFORE the trigger for some reason (see attached plots), and so they no longer pass the cluster hit count threshold. These were made using exactly the same filtered
SLIC events, and the same steering file with the same apparent thresholds in the GTP clusterer and trigger.
<br>
</p>
<p>The difference must be elsewhere in the drivers themselves.</p>
<p><br>
</p>
<p>These plots compare<br>
</p>
<p>hps-distribution-3.5-20151218.205540-15-bin.jar</p>
<p>with<br>
</p>
<p>hps-distribution-3.6-bin.jar</p>
<p><br>
</p>
<p></p>
<p>both using the 'EngineeringRun2015TrigSingles1_Pass2.lcsim' steering file.</p>
<p><br>
</p>
<p></p>
<p>A more recent 3.5 jar (1/25/2016) gives a similar number of events as Pass 4, and so the key difference must be with 3.6.<br>
