Notes. (1) Best fitting model. E = low column density error slope, L = log-normal, P = power law tail. (2,3) Peaks of log-normal parts of the N-PDF in AV. (4,5) Widths of log-normal parts of the N-PDF in units of η. (6) Deviation point in AV where the N-PDF changes from log-normal into a PLT. (7) Deviation point in AV for the change in slope from a first to a second PLT. (8,9) Slopes of PLTs.
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.
