Original 1/a for comets from samples LBn (marked by red and magenta labels on the right side of the figure) and LBg (black labels). Comets are ordered on the vertical axis according to their original perihelion distances. Three types of marks representing GR orbits are color-coded as in Fig. 8. NG solutions (triangles) are obtained using the g(r)-like function representing CO sublimation. Upward- and downward-pointing magenta triangles show orbits based on the whole data arc using r₀ = 10 au and r₀ = 50 au, respectively; small blue triangles indicate orbits using the PRE data arc; “sh” means solutions based on the distant part of the pre-perihelion data arc. On the right side of the figure, red names show comets with NG orbits determined here; magenta names indicate comets with NG orbits obtained earlier; black names show comets with indeterminable NG effects using positional data (sample LBg).
