Notes. Columns are: (1) flux notation; (2) average SEP flux for SC 22–24 (1987–2019) as taken from Table D1 of Raukunen et al. (2022); (3) the same but for SC 24 only (2009–2019); (4) ⟨F⟩∞ (see Eq. (2)) for the combined GOES and CI-based data (green curves in Fig. 1); (5) ⟨F*⟩∞ – the same as (3) but with GOES data, for SC 24 only; (6) average SEP flux reconstructed from lunar rocks for timescales of ≈106 years (Poluianov et al. 2018). Error bars are full-range for the lunar data and 1σ for other datasets. Error bars for Cols. 2 and 3 are < 1% and not shown. The data are shown in Fig. 3.
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.
