Original 1/a values for the LAn sample using the whole data arc (light red dots, 1/aori,full,GR), pre-perihelion arcs (light blue, 1/aori,pre,GR), and post-perihelion arcs (light green, 1/aori,post,GR) based on purely gravitational orbital solutions. Comets with long data arcs, perihelion distances between 3.1 au and 3.9 au, and detectable NG effects using positional data are presented (Sample LAn). Comets are ordered on the vertical axis according to their original perihelion distances; see Table 2.
