Dear all,<br><br>Please see attached files for tracking efficiencies for g17,g18 and g20 as well as event display <br>for g18 at 0% and 100% backgrounds. <br><br>For g18 tracking I have made some changes to the program to use correlation between th vs x and phi vs y.<br>
This helps to increase tracking efficiency and replay time (decreases the number of possible projection combinations). <br>The change is done in file Projection.cxx function <br><br>NodeVisitor::ETreeOp <br>Projection::ComparePattern::operator() ( const NodeDescriptor& nd )<br>
<br>Here I consider only patterns that satisfy the the aforementioned correlations between position and angles of patterns. <br><br>Vahe<br>
