Zero-level restored PI maps for the region of 94° ≤ l ≤ 129°. The superimposed bars are separated by 9′ and are shown in the B-vector direction with lengths proportional to PI and a lower intensity cutoff of 2.5 mK T_B (5 × σ_PI). Contours show total intensities running from 6.0 mK T_B, in steps of 3.6 × 2ⁿ mK T_B (n = 0, 1, 2, ...). Boxes mark strong depolarization along the periphery of the H ii regions, Sh2-131 and the G105 complex. Circles mark the depolarization H ii regions, Sh2-177 and Sh2-160.
