Properties of the large-scale magnetic field of V347 Aur for our seven data subsets. We list the average reconstructed large-scale field strength |$\langle B_V \rangle$| (column 2), the polar strength of the dipole component |$B_{\rm d}$| (column 3), the tilt of the dipole field to the rotation axis and the phase towards which it is tilted (column 4), and the amount of magnetic energy reconstructed in the poloidal component of the field and in the axisymmetric modes of this component (column 5). Error bars are typically equal to 5–10 per cent for field strengths and percentages, and 5–10|$^\circ$| for field inclinations, for the first five subsets, and at least twice worse for the last two (for which ZDI is less reliable given the sparse phase coverage).
