Range or distance and range rate or radial velocity of C/1980 E1 (Bowell), 1.0 Myr before its close encounter with Jupiter. Top panel: distribution of distances at the end of the simulations, ${28792}_{-1272}^{+1288}$ au. Bottom panel: distribution of radial velocities at the end of the calculations, 0.027±0.012 km s⁻¹. Distributions resulting from the evolution of 10³ control orbits. The median is displayed as a continuous vertical green line, the 16th and 84th percentiles as dashed lines.
