  1. Centrality Dependence of K0s production 158A GeV min.bias Pb+Pb 08A

  2. 158A GeV Standard-Cuts

  3. 158A GeV pt-spectra (efficiency)

  4. 158A GeV pt-spectra (efficiency)

  5. 158A GeV pt-spectra (yields)

  6. 158A GeV pt-spectra (yields)

  7. 158A GeV dN/dy spectratotal yield (dEdx) by na49_compil.pdf

  8. Systemmatic error study:Variation of efficiency cut

  9. Systemmatic error study:Variation of analyse cuts Good agreement at central collisions

  10. Slope Parameter

  11. Problems at peripheral collisionsmidrapitidy spectra Deviations at peripheral collisions for low pt < 0.6 GeV/c

  12. Outlook • Other systemmatic error studies • mt- spectra • 40A GeV MB • Comparision with PD preliminary results
