Only some tasks are here, there is more on the old Wiki on deltag5
- algo identifying cosmic ray passing through BTOW trigger cluster and within 3 cm from the beam line. Such ray should have 2 tracks in opposite phi, matching in in angle and position, PT may be very different. Primary event multiplicity should be very low. Mike Miller did sth like this N years ago for jets - I'll think about it.
Carl suggested this:
have you estimated the vertex finding efficiency for the restricted event class where there is a global track that points to the trigger? And for those, it would then be interesting to ask how often that global track also points to the beamline constraint. (Very occasionally, cosmics will; usually, they won't. That can provide a way to estimate that particular background contribution.) - next task ???
