Notes.
High-frequency (once per hr for 5–6 h per night) time-series photometric observations were taken over 16 nights and complemented with low-frequency (once per night) observations taken over 143 nights.
Kepler exposures are combined on board to create short-cadence timeseries (nine co-added exposures) or long-cadence timeseries (270 co-added exposures). See Koch et al. (2010) and references therein for a detailed description of the Kepler design.
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.
