Abstract: Since the magnetic structuring continues to scales of order 10–100 m, far smaller than can possibly be resolved, and since the polarization signals are weak on the quiet Sun, one needs to apply robust diagnostic techniques that do not get biased by measurement noise, are independent of telescope resolution, and have minimal model dependence, in order to reliably determine the intrinsic properties of quiet-sun magnetic fields. Such techniques make use of ensemble averages as the observable signatures of the spatially unresolved domain. Here we show how such concepts are applied to derive the field strengths, sizes, and angular distributions from the observed Hanle depolarization and from the symmetry properties of the transverse Zeeman effect.
