Notes. Young Moving Group and associations are Argus (ARG), AB Doradus moving group (ABD), Tucana-Horologium (THA), β pic Moving Group (BPMG). Membership probabilities are obtained from the BANYAN Σ online tool.


Membership probabilities are based on the BANYAN Σ-tool using optimal parallax and radial velocity for Argus group. With no prior on those quantities the membership probability is reduced to 3.4%.


Different YMGs for different a version of the BANYAN tool. The former value depicts the result from the BANYAN II tool and paper that discovered the object, whereas the latter value shows the updated group values for the BANYAN Σ-tool.

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.
