Notes. (a) For asymmetric uncertainties, we conservatively use the largest of the two values that were derived from both the statistical and systematic error analysis (see Figs. 4, 5, and A.1). (b) The final separation is calculated by adding the bias offset and combining the two error components in quadrature. (c) The final position angle (PA) is calculated by adding the bias and assumed true north offset, and combining the three error components in quadrature.
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.
