Notes. S/N is the signal-to-noise ratio per sample of the mean spectrum computed in the λ = 496−564 nm wavelength range (HERMES, FIES and HIRES spectra), or at λ ~ 570 nm (INTEGRAL spectrum), and by adopting a procedure described in Stoehr et al. (2007). The HIRES spectrum has gaps in the 477–498 and 628–655 nm domains.
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.
