Fig. 1. Mean brightness temperature of the H I gas at distances d < 1 kpc. 5 < v_LSR < 6 km s^-1. Colours indicate temperatures between 0 (blue) and 146 K (red). Overlay: E-vectors of the polarized starlight at distances d ≤ 1 kpc. The stars lie in the middle of each line, and the length of each line is proportional to the degree of the polarization (P). Depending on the degree of polarization the plot of E-vector is subdivided into three categories with different scales (circle: P ≤ 0.08%; thin line: 0.08% < P ≤ 0.6%; tick line: P > 0.6%). Loop I to IV are indicated by circles
