Notes. In addition to the parameters listed in Table D.1, we also include the angles (θ, ϕ) of the angular momentum vector, and the time elapsed since the last apocentre and pericentre, Ta and Tp respectively. The errors indicate the 16th and 84th percentiles, which were obtained from Monte Carlo realisations sampling the (statistical and systematic) errors in the observables. For each dSph we quote values derived from orbits integrated for 10 Gyr in the Galactic potentials of Models 1, 2, and 3 in the first, second, and third row, respectively. Since for Model-1 there is a significant fraction of the realisations for which Leo I does not complete one radial oscillation in the 10 Gyr of integration, the values quoted here for this dSph for this model were derived for an integration time of 100 Gyr.
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.
