    1919Note that the exact calculation of the efficiency \(\epsilon(\Delta E)\) depends on prior knowledge of the correct source spectrum \(N_0\). Therefore, it is strictly speaking only correct if the simulated spectrum and the real spectrum are identical. As the real spectrum is unknown, special care has to be taken of the systematic introduced by the assumption of \(N_0\).

     21=== Excess ===
    2122The number of excess events, for data and simulations, is defined as

    2930\[\hat N_\textrm{bg} = \frac{N_\textrm{bg}}{5}\]
    3031
     32=== Theta and Spectral Weights ===
     33
     34While the source spectrum \(N_0\) is of course independent of the zenith angle \(\theta\) of the observation, the efficiency is not, so that
     35
     36\[\epsilon(E) = \epsilon(E, \Theta\]
