Notes.

⁽¹⁾

The scaling factor is the ratio between the on and the off distribution normalized outside the signal region.

⁽²⁾

Significance is given as standard deviations and is not corrected for trials, arising from diving the data sample by eight (corresponding to eight nights with good quality data).

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.
