Notes. Null test χ2 PTEs in units percent. All tabulated PTE values, for all three Fields, fast- and slow-moving azimuth scans (denoted as “Fast” and “Slow”), are numerically computed from the RND ensemble. The last row indicates the Kolmogorov-Smirnov (KS) uniformity test PTE. The KS uniformity PTE of the entire table of PTEs is 58.7%.

(a) The χ2-value of this null test was slightly outside the simulated RND χ2-distribution and we hence only have a lower limit of 99.5% on the numerical PTE as the numerical resolution of the simulated distribution is roughly 1/183 ~ 0.5% from the RND ensemble size.
