Normalized relative χ2 versus precession rate α for (1620) Geographos and (1685) Toro. The nominal values of α = 289′′ yr−1 for Geographos (solid) and α = 356′′ yr−1 for Toro (dashed) are marked with vertical lines. The iterative convergence of the inversion algorithm is not ideal and causes some scatter of points mainly on Geographos’ curve.
