Notes. We give here the mean MJD (defined as JD2 400 000.5) of each observing night, the corresponding phase (taking φ0 at the maximum of luminosity in V), the range of baselines, the best uniform disk diameter adjusted on the squared visibility measurements, its uncertainty, and the reduced χ2 of the fit.

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.
