Notes. Comets for which new orbital solutions are presented here are shown in bold. Purely gravitational orbit solutions are marked by “GR” and non-gravitational ones are marked as “NG”, where “NG (CO)” indicates solutions based on CO sublimation. An orbit quality assessment for each comet is presented according to the modified method described in KD13. The full table is available at the CDS.
