Longitudinal magnetic field and velocity maps inferred from the Si I 10827 Å inversions of the three isolated BPs at two different optical depths, log τ = −1.0 (bottom) and −2.5 (top). Bright points (a)–(c) are shown from left to right. We note that BP (a) has opposite polarity as compared to BPs (b) and (c). Magnetic fields are clipped between −200 G and +600 G for BP (a), and between −600 G and +200 G for BPs (b–c). LOS velocities are clipped between ±4 km s⁻¹. Negative velocities represent flows along the LOS toward the observer, that is, upflows because of the proximity to disk center. The FOV corresponds to a zoom of the region-of-interest (white box in Fig. 2).
