Spatial distribution of the differences between the Gaussian separation components derived from the vector magnetogram and the lower boundary of the models. The background color map in panels (a)–(c) indicates ﹩{\rm{\Delta }}{B}_{z}^{\gt }﹩ for each of the models, and the vectors indicate ﹩{\rm{\Delta }}{{\boldsymbol{B}}}_{h}^{\gt }﹩. Panels (d)–(f) show similar plots for ﹩{\rm{\Delta }}{B}_{z}^{\lt }﹩ and ﹩{\rm{\Delta }}{{\boldsymbol{B}}}_{h}^{\lt }﹩. The background color map in panels (g)–(i) shows ΔJ_z, with the vectors indicating ΔB_T. The green contours in each panel indicate the main PIL.
