LVL2 trigger plan for run4-AuAu

(1) select all PC3 hits in aerogel shadow;(2) 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;
