I have looked into the problem Hiro reported on not getting the right #participants from the .zdat files.
There is a problem now fixed but of course not for the existing files on the data disks.

a) The Number of Neutron spectators was not done right.
    Hijing in fact does not distinguish between N and P when calculating spectators. Therefor I had set
    #spects(P) = Z/A*Nucleon spectators for target and projectile but made an error in calculating the
    #spect(neutrons).
b) In the existing file the npproj and nptarg as stored in the zebra files is in fact correct (as used in dndy.f program)
    and one can resurrect the total participants using the spcifications from above.
c) During fixing this stuff the 130-0-15 file was overwrittem, but is now being generated again.
