Accuracy of the uncertainties of NEV_eq and NEV_b, for a range of different count rates, number of bins, and types of PSDs. This figure used the results of the same simulated light curves as are displayed in Fig. A.4. The parameter NEV_m denotes a NIV estimate, which is either NEV_b, or NEV_eq. The parameter σ_m denotes the uncertainty in the measurement. The black dashed line at a value of $\sqrt{2/\pi }$, indicates the level that |NEV_m – NIV| /σ_NEV,m = |Z_m| should have. This figure excludes points from simulated light curves with very negative values of NEV_eq for which the error cannot be determined. Other features are similar to those of Fig. A.4.
