See slide 8 in the attached document, posted to docdb. The agreement between the two simulations is acceptable (30ps difference in the fit p0, probabably within MC systematics. The primary message of this plot is the large time-walk that exists in the simulated shower times after all corrections have been applied. This is the time recorded in REST within the fcalShower objects.<div><br></div><div><a href="https://halldweb.jlab.org/doc-private/DocDB/ShowDocument?docid=3852">https://halldweb.jlab.org/doc-private/DocDB/ShowDocument?docid=3852</a><br></div><div><br></div><div>-Richard Jones</div></div>
