Top: examples of meridional spot redistributions during the covered timespan of about 43.5 days at arbitrarily chosen quadrant longitudes of 25°, 115°, 205°, and 295° (top: left, right, below: left, right, respectively). In each case, the replacements of the maximum temperature offsets (dots) are fitted with a 1st degree function. Bottom: all the 72 available line fits. Red (thick) line indicates their average slope, suggesting a common poleward flow of per rotation period, consistent with the result shown in Fig. 4.
