  26. LVL2 trigger plan for run4-AuAu • select all PC3 hits in aerogel shadow; • select all PC1/PC3 tracks with reasonable • vertex cut (say BBC+-10cm); • (3) cut on momentum (we'll have ~5% resolution); • (4) check for a RICH ring; • (5) match hit to EMC cluster; • (6) match to the hists in aerogel, use both timing • and amplitude; • (7) use all this information to make a decision; collaboration meeting in Nashville, Jun 10-13 2003
