Notes.
α was inferred from other data sets (see Sect. 2.2).
The table lists: the time of the first slit position (UT), the heliocentric angle at the center of the field of view (FOV) (γ), the values of the straylight scaling factor (α), manually found intensity value at which the contour between penumbra and umbra is calculated (I°, rounded numbers). This data can be accessed openly via sdc.leibniz-kis.de.
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.
