Notes. The successive columns signify (1) – comet designation; (2) – epoch, that is, osculation date; (3) – perihelion time [TT]; (4) – perihelion distance; (5) – eccentricity; (6) – argument of perihelion (in degrees), equinox 2000.0; (7) – longitude of the ascending node (in degrees), equinox 2000.0; (8) – inclination (in degrees), equinox 2000.0; (9) – reciprocal original semi-major axis in units of 10-6 AU-1. Original orbits determined using the NG model of motion are indicated by light grey shading.
