with HDGeant4</span></h3>
<p>Sean summarized the status of recent comparisons of
simulation from HDGeant versus those from HDGeant4. He
has made a <a rel="nofollow" class="external text"
href="https://logbooks.jlab.org/entry/3470274">log
book entry</a> with links to plots comparing results
from the monitoring histograms. He has also opened an <a

href="https://github.com/JeffersonLab/HDGeant4/issues/10">issue
on GitHub</a> on the topic of FCAL timing. Elton,
Simon, and David are also making comparisons for charged
tracks, especially those in the forward direction. Elton
