Notes. The first two terms in the systematics model column show the polynomial degree for time and orbital phase; the third term shows the name of the jitter vector (which is always modeled as a linear polynomial). The absence of a third term indicates that no jitter vector was included.

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.
