Iterative internal calibration flowchart. The process is started by bootstrapping the reference source photometry from the raw transits, and it then proceeds by iteratively deriving new flux calibrations, which are then used to produce an updated set of reference fluxes. The calibration loop is represented by the three processes labelled A, B, and C; the dataflow is represented by thicker arrows. See the text for additional information.

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.
