hoxw to tag a "secondary" vertex
September 30, 2015 10:48 AM
crossing (far left bottom) of 2 tracks makes me think that true secondary vertex is the one tagged, when weird one, close to center, isn't.
many tracks missed(?) by computer on the central vertex
maybe an off-vertex of 2 very close tracks under (bottom) the central vertex
if blue track sign an off-vertex very close to the central, then 2 tracks have been probably missed.
the weird tag maybe a secondery vertex (of 2 tracks) of the tagged vertex (also of 2 tracks). image difficult to interpret
