Descripción
Three different maps of the quiet Sun, observed with the Advanced Stokes
Polarimeter (ASP) and the Diffraction-Limited Stokes Polarimeter (DLSP),
show evidence of strong (~=1700 G) and weak (<500 G) fields
coexisting within the resolution element at both network and
internetwork locations. The angular resolution of the observations is of
1" (ASP) and 0.6" (DLSP). Even at the higher DLSP resolution, a
significant fraction of the network magnetic patches harbor a mixture of
strong and weak fields. Internetwork elements that exhibit kG fields
when analyzed with a single-component atmosphere are also shown to
harbor considerable amounts of weak fields. Only those patches for which
a single-component analysis yields weak fields do not show this mixture
of field strengths. Finally, there is a larger fractional area of weak
fields in the convective upflows than in the downflows.
