H I-orientation data integrated in the velocity range v_LSR ∈ [−60.45, −44.99] km s⁻¹ toward our surveyed area. The background color shows the H I intensity on a linear stretch, and the texture represents the POS magnetic field orientation inferred from HI fibers. The red segments indicate the mean POS magnetic field orientation obtained from starlight polarization tomography for clouds with distances larger than 1 kpc, as in Fig. 16. The white-dotted circle shows the “2-cloud region” studied in Panopoulou et al. (2019). The magenta contour and the blue circle are as in Fig. 10.
