Notes. Preferred models are marked in Col. [15] as “YES”/“’YOS” (orbit based on full data-arc), where preferred NG solution based on g(r)-like function describing CO sublimation is marked as “YOS”, or as “YE1”/“YE2” (for orbit based on pre-perihelion or post perihelion data arc, respectively). An asterisk in Col. [11] indicates asymmetric NG solution. The last row for each comet presents data used inthe Minor Planet Center and Nakano Notes (if existing) for orbit determination and resulting original and future 1∕a (taken from these websites in March–June 2019). The observational material taken for osculating orbit determination is described in Cols. [4]−[8] and [12], whereas Cols. [9] and [10] give Q^* for GR and NG model of motion, respectively, and the resulting orbit quality assessment (orbital class) is given in Col. [11]. 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” means that all observations were taken before the perihelion passage, “pre+” means that considerably more pre-perihelion measurements were available, and additional “+” means a drastic dominance of data before perihelion. Columns [13], [16], and [17] are explained in Table A.1. ⁽¹⁾See Sekanina (2019). The full table is available at the CDS.
