Resulting χ² map of the X and Z scan for the solar data fitting of Γ₁ between 0.72 R_⊙ and 0.91 R_⊙. The orange crosses indicate the positions of the AAG21 model including rotation and magnetic fields, and the red crosses indicate the MB22 standard solar model (MB22-Phot in Table 2). Values are from their paper. The upper panels used the A2 model, and the lower panels used the M1 model. The left panels used MB22 individual elements, and the right panels used AAG21 individual elements.
