Panels a and d: distributions of cosi_E where i_E is the ecliptic inclination; panels b and e: distributions of the Galactic argument of perihelion ω_G ; panels c and f: distributions of the Galactic longitude of the ascending node Ω_G. Panels a–c:original orbit at the observable perihelion passage; panels e–g: orginal orbit at the previous perihelion passage. Foreach plot the black line is for all observable comets, the red line for jumpers, the blue line for creepers, the orange line for KQ-jumpers, and the magenta line for the KQ-creepers. The data are obtained from observable comets from the D0proto-Oort cloud.
