Minimum and maximum vector sum resulting from shifting a single active region in longitude. Left: Total vector sum. Right: Equatorial component of the vector sum. The shaded region shows the minimum-maximum range. The solid blue line shows the unaltered simulation. The red dashed line shows the location of the solar maximum (CR2149, April 2014, SILSO 13-month smoothed mean). The dashed black line in the left panel shows the strength of the axial component.
