Fig. B.2


Formal uncertainties versus the G magnitude for sources with a five-parameter astrometric solution. Left: semi-major axis of the error ellipse in position at epoch J2015.5. Middle: standard deviation in parallax. Right: semi-major axis of the error ellipse in proper motion. The yellow dots show individual values for a representative selection of the sources; the cyan curve is the median uncertainty and the blue curves are the 10th and 90th percentiles. The plotted sample contains all sources for G < 11, and a geometrically decreasing random fraction of the fainter sources with roughly uniform distribution in G.

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.
