| 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. |
