Notes. We recall that these values correspond to a physically motivated, yet purely empirical model. We list them here for reproducibility. The parameters of individual components might not have a direct physical interpretation. Exceptions to this are the widths of the exponential wings, which are much less degenerate with other components because they extend over a broader range of wavelengths than the rest (see Figs. 2 and 3).
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.
