Simulated maps obtained with the kinematical model for a galaxy thin disc with an exponential brightness profile defined by a scale radius R_D = 0.125″ and dynamical mass M_dyn = 5.0 × 10¹⁰ M_⊙. The flux, velocity, and velocity-dispersion maps along the LOS are indicated by F(x_p, y_p′), V(x_p, y_p′), and σ(x_p, y_p′), respectively. From top to bottom panel: disc inclination and position angle (β, γ) are, respectively, equal to (40, −45) deg, (40, 0) deg, and (60, 45) deg. The other parameters defining the model are: the FWHM of the synthesised beam (0.4″ × 0.275″), the position angle of the beam (B_PA = −50 deg), the FWHM of the LSF (σ_LSF = 20 km s⁻¹), the bin size (0.05″ × 0.05″), and the angular radius of the disc (R = 1.25″). The number of clouds used in this model is N_p = 7.5 × 10⁶.
