Notes. Column 1 lists the abbreviated satellite name (in the same order as in Table 1), Col. 2 its Galactocentric distance, Cols. 3 and 4 give the proper motion we obtain followed by the statistical error and the second systematic error, Col. 5 the correlation coefficient between μα, * and μδ, Col. 6 the heliocentric systemic VLOS (the source of which is typically the same as the spectroscopic catalogs we adopt); Cols. 7, 8, and 9 list the Galactocentric 3D, radial and tangential velocity, and Galactocentric velocity, respectively. In some cases the errors are large, and due to the existing correlation between the two proper motion directions, we note that for detailed calculations it is best to start from the measured quantities (i.e., the proper motions).
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.
