Distribution of the line ratios with respect the distance from the midplane for the IC1553 galaxy. The star-shaped, triangular, and square markers represent the line ratio at that z for MAD = −2.5, 0, and 3 kpc, respectively, analogous to a long-slit perpendicular to the galactic plane at a given MAD. The solid lines represent the integrated values along the major axis distance. The dashed black line represents the Σ_Hα height distribution of the galaxy. The grey background between z = −0.7 kpc and 0.7 kpc represents the galactic plane.
