     27In addition, the observed differential flux depends on the zenith angle. That means that for a correct calculation of the efficiency, the number of simulated events per zenith angle interval has to match the observation time distribution.

    31 That means that for a correct calculation of the efficiency, the number of simulated events per zenith angle interval has to match the observation time distribution. This can be achieved by applying zenith angle dependent weights \(\omega(\theta)\) to each simulated event. Similarly, the discussed requirement of the match between result spectrum and simulated spectrum can be achieved applying energy dependent weights \(\omega(E)\).
