Kinematic and structural parameters of NGC 4593 as a function of radius. Top row, from left to right: Rotation Velocity (V_rot), Velocity Dispersion (σ_gas), and Surface Density (Σ). Bottom row, from left to right: Inclination Angle (i) showing the variation of inclination with radius, Position Angle (ϕ) illustrating the fluctuation of position angle with radius, and Radial Velocity (V_rad) displaying the radial velocity (km/s) versus radius, marked in grey. In each subplot, the observational data are represented by grey points with error bars. The fitted azimuthal normalisation with V_rad = 0 is depicted by an orange line with a dash-dot pattern, while the local normalisation series with V_rad = 0 is shown as a solid green line. The local normalisation with V_rad ≠ 0 is represented by a dashed red line, and the azimuthal normalisation with V_rad ≠ 0 is indicated by a dotted blue line.
