Systematic uncertainties in MonteCarlo simulations of the atmospheric muon flux in the 5-line ANTARES detector

摘要

The ANTARES detector was operated in a configuration with 5 lines for aperiod of 10 months from February until November 2007. The duty cycle wasbetter than 80% during this period and almost 2*10**7 atmospheric muon triggerswere collected. This large sample was used to test Monte Carlo simulationprograms and to evaluate possible systematic effects due to uncertainties onenvironmental parameters and detector description. First results are presentedand discussed.
