Table 1: Atomic parameters of the Fe I lines.
Table 2: Fraction of irregular Stokes V profiles of the Fe I 15 648 and 6302 Å lines as a function of the average unsigned magnetic field $\langle B\rangle$ in the simulation snapshots. The last column gives the number of the single-lobed Fe I 6302 Å profiles. All profiles are classified irrespective of their amplitudes.
Table 3: Fraction of irregular Stokes V profiles of the Fe I 15 648 and 6302 Å lines with reduced resolution as a function of $\langle B\rangle$ . All profiles irrespective of their amplitudes are classified.
Table 4: Fraction of irregular Stokes V profiles of the Fe I 15 648 and 6302 Å lines with reduced resolution as a function of $\langle B\rangle$ . Only the profiles with amplitudes 3 times above the noise of $3 \times 10^{-4} I_{\rm c}$ are considered. The last two columns give the fraction of profiles above the threshold in the infrared and the visible.
