Notes. For ten synthetic spectra the real stellar parameter values are given together with the results from methods (1), (2) and (3) (see Sect. 3.2.3 for more information). Values that deviate from the actual value with (little) more than the uncertainty are marked in bold. The errors are approximately symmetric except when a different upper and lower bound are given.
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.
