exercise full triggering with all major systems
Integration Goal 1 dual muon crates,
initial muon triggering/filtering, ship data to
farm, run reconstruction, online event display
Integration Goal 2 Initial triggering on L1
CFT/CPS, begin linking tracks in CFT/CPS/CMuon,
begin Level 2 trigger integration
Integration Goal 4 Full detector in
steady-state Cosmic Ray Commissioning
Integration Goal 3 Add Central
Calorimeter to commissioning stream, most major
systems being commissioned
Begin full central muon system, integrate Level 2
muon trigger at DAB test stand
