Phase folded BRITE light curves (after subtracting the non-rotational variability; upper two panels) and longitudinal magnetic field measurements from LSD profiles with various line masks, using a P_rot = 2.95333 d and T₀ = HJD 2455702.5, and indicated by the observing campaign (black for MiMeS, red for BRITEpol, and green for ESPaDOnS). The pure dipole model for the geometry of the large-scale magnetic field of Eq. (3) is indicated by the dashed blue line and the dipole with a quadrupole contribution of Eq. (4) is indicated by the solid black line. Note the differences in strength of the measured B_l values for the various LSD line masks.
