Notes. The successive columns signify (2) epoch, i.e. 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. In the last line we present for each comet the difference between the nominal and catalogue values of a given element divided by the respective combined error, thus Diff
