Velocity maps of the warm gas in the ten galaxies in our simulated data sample with (top two rows) and without (bottom two rows) AGN feedback at z = 1.3. Each galaxy is oriented edge-on, each map has an extent of 10 × 10 kpc, and the colors scale between −350 km s⁻¹ and 350 km s⁻¹. The line extending across the maps is oriented at the median position angle of the best-fitting ellipses within 1.5 r_e. The solid portion of the line has the length of the galaxy’s effective radius from the center along the major axis, while the dotted portion represents the remaining fit portion up to 1.5 r_e. The plotted ellipses are the best-fitting ellipses at every radius; the ellipses’ flattenings and position angles were allowed to vary between radii. The standard deviation of these ellipses’ position angles is σ_PA, and the position angles were compared with those of the stellar velocity to compute Δϕ. We note that k_3, 5/k₁ was calculated based on a different set of ellipses at the same radii with fixed position angles (all oriented along the solid line) and flattenings (the median flattening of the first set of ellipses). The linestyles of the ellipses correspond to the values of the irregularity parameters as follows: a solid line means that both k_3, 5/k₁ and Δϕ are within the regular ranges, a dotted line means that k_3, 5/k₁ is irregular, a dashed line means that Δϕ is irregular, and a dashed-dotted line means that both are irregular.
