Proper semimajor axis (a) vs. proper sine of inclination (left) and proper eccentricity (right) for the eight primitive families in the inner main belt. The high-inclination families studied in this work are Klio (brown crosses, ×), Chaldaea (pink plus signs, +), Chimaera (grey diamonds, ♢), and Svea (yellow squares, □). The blue dots are the asteroids with computed proper elements present in the inner main belt, and the black lines limiting this region represent the ν₆ and 3:1 resonances.
