Notes. The intervals indicated between parenthesis are computed on the basis of the χ2 following Avni (1976). They provide the 68% confidence interval (unless the limit of the range investigated is reached, in this case, the limiting value is the limit of the explored range since all the explored values are within this 68% confidence).
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.
