6/15/99 - Continuation of study of hits in detector for B on and B off:

Field off central events (Venus) - 20 events:

Field on central events (Hijing) - 20 events:

same field on sample, vertex dist.:

Ratio of hits/layer and hits/sensor (for findable tracks) for two samples above.

The ratio is of (B off sample)/(B on sample).  Ratio is one if sensor number is not used.  Zero means no hits in field off sample.
