Impact parameter distributions from UrQMD for C+C at 1 and 2 A GeV, and Ar+KCl at 1.76 A GeV

for: 1. min. bias events (at least one nuclear interaction)
     2. LVL1 (mult_charged>=4 for CC and mult_charged>=16 for ArKCl)

LVL1 event selection:

estimated from simulations: UrQMD events passed through Geant, detector digitizers and LVL1 trigger emulator

1 row contents: imp.par (center of bin, in fm), yield,

Normalization:

arbitrary, preserves LVL1/min.bias ratio 0.517 and 0.603 for CC at 1 and 2 GeV, respectively, and 0.345 for ArKCl

data are published in:
