Notes. (1) Nomenclature adopted to denote the different simulations. (2) The nature (observed or synthetic) of the spectra that are perturbed. (3) Type of perturbation. (4) Amplitude of the perturbations. For C runs, we list the amplitude of the variations at λg. Each of the 1638 spectra from CALIFA 277 were perturbed ten times according to each of these 14 recipes.
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.
