Notes. The second column gives the theoretical position of the line in Å, the third column contains the logarithm of the temperature of the maximum ionization fraction of the given ion in K as given in the CHIANTI atomic database. The fluxes (I) and their errors (Δ I) in erg s-1 cm-2 st-1 are given in columns four and five.
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.
