Distribution of the complete spin pole solutions for the primordial family members. The main plot is a sinusoidal equal-area cartographic representation, where the vertical grey lines define the longitude (λ) and the horizontal curves define the latitude (β). The right histogram represents the latitude (β) of prograde (red) and retrograde (blue) rotators. The bottom histogram represents the longitude (λ) of prograde (red) and retrograde (blue) rotators. The specific values for each asteroid are shown in Tables B.3 and B.4.
