Tentative surface magnetic map of RZ Ari reconstructed with ZDI; see section 4.2. The three components of the field in spherical coordinates are displayed from top to bottom (flux values are labeled in G). The star is shown in a flattened polar projection down to latitudes of −30°, with the equator depicted as a bold circle and parallels as dashed circles. The radial ticks around each plot indicate phases of observations. For this reconstruction, we used P_rot = 530 d and an inclination of the rotation axis with respect to the line of sight i = 40°
