Pole direction and obliquity distribution of (7025) 1993 QA. Left: polar projection of the southern ecliptic hemisphere showing the possible pole directions of asteroid (7025) 1993 QA. The global best-fit pole direction for Psid = 2.506299 h is indicated by the red circle, and the best-fit pole direction for the second-best period the blue circle. The combined 3σ uncertainty region is shaded in gray. Right: histogram of obliquities corresponding to all accepted pole directions within the 3σ uncertainty range, weighted by their respective χ2 values and binned in 5° intervals. The dashed red line represents the obliquity of the nominal pole direction.
