Notes. Columns are: object, date of observation (number of spectra taken on that date), equivalent widths and column densities from the mean weighted spectra of each date. Total refers to the values obtained from the weighted average spectrum built using all the available spectra for each object; these values appear as EWaverage and Naverage in Table 2.
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.
