       Dear Bjorn,
               thanks very much for your plots, ie
   www.fys.uio.no/~bjornhs/ZDCcorr_MultEff.ps
   It looks like the
   ZDC strong cut is only accepting semicentral and central events.
   What was the data that went into analysis? To check the efficency
   of this cut it would be necessary to look at trigger 4 triggers.
   Also to see the efficency could you please plot the ratio of 
   (ZDC Strong Cut)/(ZDC weak cut) versus tile multiplicity.
   If this could be done for different triggers it would allow us
   to check the efficency for a wide range of multiplicities.
                       Yours Michael
