Comparison of the mock catalog’s (orange) and 4FGL’s (blue) pulsar properties with respect to four spectral parameters and the energy flux E₁₀₀ within the range from 0.1 to 100 GeV. The latter quantity is displayed in the upper left panel, while the flux density F_0, PSR is shown next to it. The remaining PLEC parameters are the pivot energy E₀ (center left panel), the low-energy spectral slope Γ (center right panel), the exponential index b (lower left panel) and the exponential factor a (lower right panel). The y-axis of the E₁₀₀-distributions is given in actual object numbers whereas the other four panels show the normalized distributions of the respective parameters.
