Vertical stratification of the vertical component of the magnetic field, B_z(z), along the two positions in Fig. 4 (see vertical white dashed lines). The red and orange colors correspond to the results along the spine from the MHS and MHS + ∇ ⋅ B = 0 inversion, respectively. The shaded pink areas indicate the 3σ_Bz confidence level from the MHS inversion. Similarly, the blue and steel blue colors correspond to the results along the intraspine from the MHS and MHS + ∇ ⋅ B = 0 inversion, respectively. The shaded cyan areas indicate the 3σ_Bz confidence level from the MHS inversion.
