Notes. The dates (and the start times below) of the FCS observations that were selected and averaged for this analysis are shown. The second column indicates the NOAA number. The third column indicates the nature of the count rates in the SMM BCS Ca xix channel. The fourth column indicates whether the neon abundance was found to be high, standard (Std.), or low by Schmelz et al. (1996). The last column shows our measured FIP enhancement of iron with respect to neon and oxygen, relative to the Asplund et al. (2009) photospheric abundances, and assuming that neon and oxygen do not vary.
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.
