Bootstrap distribution of the pole direction in the ecliptic longitude λ and latitude β (top), the YORP parameter υ, and the rotation period P₀ (bottom) for asteroid (138852) 2000 WN10 (the latter at epoch JD₀ 2457022.5). The color-coding corresponds to the density of points, and the cross marks the solution based on the original (not bootstrapped) data set. Pole ecliptic latitudes β higher than 90° correspond to pole directions β − 90°, λ − 180°.
