Doppler (top) and magnetic (bottom) temporal cuts centred on the 13 selected persistent downflows. The time (vertical axis) stands for 24 h, the spatial axis (y cut, horizontal) is 15″ for each column and the numbers indicate the labels of the selected downflows corresponding to the bottom right of Fig. 4. The persistent downflows move across the surface but are visible in the cuts at least from 3.5 h to 20 h.
