Composite picture of the influence of cometary and stellar uncertainties on the K2 orbit recorded at the previous perihelion passage. Blue dots mark 5001 K2 clones perturbed by all stars on their nominal tracks. Orange dots represent the nominal K2 orbit perturbed by 10 000 P0230 clones. Black dots present 10 000 pairs of K2 and P0230 clones. The red marginal distribution histogram of q_prev corresponds to the black cloud of points. The result for nominal stellar and cometary data is in the center of the green circle. Omitted are 226 outlier points from the far right tail of the black swarm and 219 from the orange one.
