Photo of the event-of-the-day for Mon 10 May, 2003.
This is a fairly confusing event if you look at just MCTR data. It becomes clear when looking at the space points (drawn in red on the figure) that there are two distict large energy loss points. The event classification also did not notice that there was a beam positron, but the pctof was 54ns, so could possibly be identified in the root trees. Another issue is that the helix fit (not shown) was to the last section of the decay positron's helix.
