NG parameters A₁, A₂, and A₃ (in units of 10⁻⁸ au·day⁻²) for the selected NG orbits described in Sect. 4.2 for C/2000 SV₇₄ from the sample LAn; uncertainties in the NG parameters are listed on the lines below each set of values.

Notes. Differences in the NG parameters between the CODE catalog and this study are only due to a different approach to data weighting. The last column gives the asymmetry in NG parameters between the PRE and POST orbital legs.
