Variation of orbital parameters and the Cartesian velocity in the z-direction. In each panel, the orange curves represent nongravitational accelerations of 10⁻⁵ au day⁻², and the green, brown, and navy-blue curves represent nongravitational accelerations of 10⁻⁶, 10⁻⁷, and 10⁻⁸ au day⁻². Here, we plotted the behavior of 50 clones to keep the image size manageable.
