Appendix 2—figure 2. Simulations for different values of K, the number of bins in the alignment distribution.

${\displaystyle \mathrm{X},\mathrm{Y}}$ normal distributions with different ${\displaystyle {\sigma }_{\mathrm{x}},{\sigma }_{\mathrm{y}}}$ and constant ζ = 15°. K = 4, 7, 11, 15, 22 were examined. (A–B) Global (A) and local (B) indices grow with K. (C–E) Relative contribution of LI to the observed alignment (C), Retrieved estimated ${\displaystyle \zeta }$ (D) and accuracy of estimated ${\displaystyle \zeta }$ (E) stabilizes for K ≥ 11.
