Notes. Columns from left to right: segment number, start and end time epochs for the segment in HJD – 2 400 000 and corresponding dates, length of the segment in days ΔTseg, length of the longest gap ΔTgap in days, number of observations N, number of modulators L, goodness of fit R2 and the type of the event that could be detected in the segment (if any). NA stands for the segment with not enough data points for meaningful CF analysis, “–” for smooth phase behavior, “+” for disrupted phase behavior of flip-flop type, “?” for disrupted phase behavior that can not be associated with a flip-flop type event, and “/” for phase drifts.

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.
