Notes. The observations are identified by the Julian date of the middle of the exposure. The following columns denote exposure time and signal to noise ratio. Equivalent width (W) measurements obtained by the numerical integration are summarised in the second part of the table. The error estimate is adopted from Vollmann & Eversberg (2006). The values plotted in brackets were not used for the analysis due to the low spectra quality. The radial velocities of the iron lines are not present in this table, because they were not analysed due to their complicated structure (Fig. 17). The measured values can be found in Kučerová (2011).

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.
