Notes. Best-fit parameters were derived from our MCMC using the median and the 16th and 84th percentiles to estimate the uncertainties. Columns 7-9 show the standard deviation of the major axis, the standard deviation of the minor axis, and the position angle of the deconvolved elliptical Gaussian.

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.
