Average kernel velocities \(\left\langle | {v}_{{\rm{slip}}}| \right\rangle\) and the standard deviations \({\sigma }_{| {v}_{{\rm{slip}}}| }\) (in kilometres per second), calculated using the average orientation of the detected features, are indicated. Different columns of the table designate the three quantities determined using time–distance diagrams saturated to selected intensity thresholds (10–90% of the maximal intensity \({I}_{\max }\)).
