Notes. We report, for each transition, the average and standard deviation of the best fitting results. For those systems where different regimes are identified, we also report the separate means and standard deviations. a - J1118 data marked with this note are the mean and standard deviation after removing the outlier from epoch 9. b - J0422-A data marked with this note are the mean and standard deviation after removing the outlier from epoch A4. c- J0422-B data marked with this note are the mean and standard deviation after removing the outlier from epoch B3. d - J1807-A includes the mean and standard deviation of the first three epochs, as the S/N of later observations was too low.

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.
