Figure 2: Upper part: I, Q, U, and V profiles of Fe I 6301.5 Å  ( left) and Fe I 6302.5 Å  ( right). The observed profile (thin line) is compared with the profile computed by SIR (thick line). The arrow in the white-light image points to the location from which the profiles were obtained, a broad part of LB1. Lower part: the stratification of T, |B|, and (solid line) and the range of errors (dotted line). The dashed line in the B stratification corresponds to a different stray-light profile.
