Notes. The set of our new data derived in Sect. 2 is listed at the bottom of this table, which is labeled with db = OCNS. Here, db, df, site, ts, rfs, and obs are the items defined in OCNS2019. For each reference, S gives the list of involved satellites, where the characters T, N, I, and O denote Triton, Nereid, the set of inner satellites (obsTrg = 805–808, i.e., Despina, Galatea, Larissa, and Proteus), and the set of outer satellites (obsTrg = 809–813, i.e., Halimede, Psamathe, Sao, Laomedeia, and Neso), respectively. C, A, R, P are astCat, aberr, refrac, and phase, respectively. N and Ng are the number observed coordinates and observation nights, respectively. Statistics for (O − C) residuals (rsdIcrsA) after removing star catalog bias with respect to Gaia-DR2 are given in the last four columns. μ1 and σ1 are the mean and standard deviation, respectively, of the residuals in the first component of rsdIcrsA, and μ2 and σ2 the second component. The ephemerides used in calculating C are DE438/NEP081xl for Triton and Nereid, DE438/NEP090 for inner satellites, and DE438/NEP086 for outer satellites.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
