Notes. The different filters are ordered by central wavelength. The errors are computed with respect to the SPIPS results and to a value from the literature. The statistical parameters are provided on the 75 stars of the gold sample. Not all the stars have literature values.

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.
