Profiles of the field-line inclination angle (angle to the vertical direction, in degrees, from −90 to 90) as a function of the distance to the surface for flux-tubes at different latitudes and at five different instants of the cycles (from the top to the bottom panel: t = 0, 2.75 ,3.30, 3.85, 4.40 yr). The diamonds mark the position of the maximum inclination for each flux-tube. The times and colour scheme are the same as in Figs. 5 and 6.
