Notes. Columns 2 and 3 list the quadratically averaged large-scale field (<BV>) and small-scale field (<BI>) over the stellar surface. Column 4 gives the time-averaged small-scale field integrated over the visible hemisphere (<BS>). Columns 5 to 7 list the polar strengths of the dipole component Bd, the tilt of the dipole component to the rotation axis and the phase toward which it is tilted, and the amount of magnetic energy reconstructed in the poloidal component of the field and in the axisymmetric modes of this component. Typical error bars on field values, percentages and dipole tilts are equal to 20%, 10%, and 10° in 2024 and 2025, and twice as much in 2021 due to the sparser sampling.
