Evolution of loss and rotation parameters with rejected star number, k, increasing in the full dataset (0 < G < 13). (a) Max Q_i(x) in the solution (star names labeled). (b) $χ_{red}^{2}$ $\chi_{\text {red}}^{2}$ of the solution. (c) Estimated orientation parameters. (d) Estimated spin parameters. The error bars are formal uncertainties directly derived from the covariance matrix.

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.
