Well, here may be the one of the root of the problems.
Since we know and knew that ZDC response for central collisions would be
marginal
the triggers were changed for the low energy AuAu to be
tr 2:  BB.trfs.h1
tr 6: ZDC.trfs.h1 (as for fll energy running).
So if you have used tr6 for selection w/o correcting for loss of yiled there
can well be a problem


extract from e-log:


 Wed Mar 24 10:12:58 2004 -setup shift for 62 geV
 10:17:25-  trigger setup
Trigger 2 is now BB.TRFS.H1 (not full fs) Trigger 1 is BB.L.R >=2; - fv
 Thu Mar 25 16:09:14 2004 -shift
 17:54:47-  triggers
The trigger 1 was changed to be BB.L.R>=1 The trigger 2 is BB.TRFS.H1 (with
RC). This was changed from bb>=2 to BB>=1 before this prev min bias run. -
