Evolution of the values of the semi-major axis (a, top panel), eccentricity (e, second to top panel), inclination (i, third to bottom panel), ascending node (Ω, second to bottom panel), and argument of perihelion (ω, bottom panel) of 2023 DZ₂. The panels display the results of integrations for the nominal orbit (in black) and those of control orbits with Cartesian vectors separated ±3σ (in light green, −3σ, and green, 3σ), ±6σ (in cyan, −6σ, and blue, 6σ), and ±9σ (in pink, −9σ, and red, 9σ). The output time-step size is 4.383 h. The source of the input data is JPL SBDB and they are referred to the standard epoch JD 2460000.5 (25 February 2023) TDB, which is the origin of times.
