Top: Distribution of donut lifetimes (left) and distribution of donut areas corrected for projection effects (right). Bottom: Distribution of mean velocities inside donuts (left) and percentage of the area with a velocity greater than 0.5 km/s in donuts (solid line) and in the complementary field (dashed line) at the disk center ±20° in latitude and longitude (right). These distributions come from data from 29 November 2018.
