Notes. N is the number of observations by each satellite for each coordinate. Observations with residuals higher than 5 pixels were discarded. “MM centroid fitting” refers to the fitting technique presented in Zhang et al. (2021).
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.
