Statistics for 125 LPCs with the osculating perihelion distance greater than 3.5 au described in Sect. 6.1. Upper panel: the distribution of previous 1 /a, where the filled grey histogram represents calculations with Galactic tide perturbations (stellar perturbations are ignored), the black-lined histogram represents results including perturbations from all stars except HD 7977, and the red dashed histogram describes the case with perturbations from the Galactic tide and all stars. The light-grey vertical band shows the area traditionally called the Oort spike. The middle and lower panels show the distribution of the previous perihelion distance; the lower panel gives details about the first bin (1–100 au) of the middle panel.
