Notes. The sample includes comets with first-quality orbits or NG orbits in MWC 08 and those discovered during the years 2006–2010. The observational material of comets taken for osculating orbit determination is described in Cols. (2) − (8) and (13), whereas the new orbit quality assessment resulting from the osculating orbit based on these data sets is shown in Cols. (10) − (12). The second and third columns show an osculating perihelion distance and perihelion time. The data distribution relative to a perihelion passage is presented in Cols. (7) and (8), where “pre!” (“post!”) means that all observations were taken before (after) perihelion passage; “pre+” (“post+”) means that significantly more pre-perihelion (post-perihelion) measurements were available, and an additional “+” indicates the drastic dominance of pre-perihelion (post-perihelion) measurements in both the number and the time interval. Column (9) shows the type of the best model possible to determine from the full interval of data, where the subscript “un” indicates that the GR and even the NG model determined from the entire interval of data are not satisfactory in the sense of the three criteria described in detail in Papers 1–4. For such an unsatisfactory orbital solution the better model for pre-perihelion motion (that based on some subsample of data) is given in the second line of a given comet, except for comets C/1990 K1 and C/1993 A1, where no individual data treatment has been applied yet. Columns (10) and (11) give the Q∗ for GR and NG models, respectively. The orbital class resulting from the model described in Col. (9) and determined according to the new quality assessment is given in Col. (12). References to publications in which dynamical studies were based on the orbital solution presented here are listed in the last column, where P1 refers to Królikowska & Dybczyński (2010), P2 to Dybczyński & Królikowska (2011), P3 to Królikowska et al. (2012), and P4 to Królikowska & Dybczyński (2013). Many additional notes to individual objects are appended to this table, and the remark “new” indicates solutions that have not been used in P1–P4. Notes in Col. (14):
many more observations were used here than were used for the MWC 08 orbit or the orbit given at the IAU Minor Planet Center Database (2013) (as of May 2013).
Significantly fewer observations of C/1952 W1 was available for us than were used for the MWC 08 orbit determination.
This new solution is based on a data interval three days longer and containing 4 more observations than the orbit analysed in Paper 2.
Orbit is based on a data interval ~8.5 months longer and containing 3 more observations than that analysed in Paper 2.
Orbit is based on a data interval ~3 weeks longer and containing 4 more observations than that analysed in Paper 2.
Orbit is based on a data interval ~1.6 yr longer and containing 4 more observations than that analysed in Paper 2; this results in an increase from quality class 1a to 1a+.
