Galactocentric radii r_vmax that contribute to the LOSVD the maximal velocities according to Eq. (16), which was used in the derivation of the approximative maximal/minimal LOS velocities (Sect. 5, point 3) – orange curve, according to the approximative LOSVD (Sect. 5, point 2) – purple curves, and according to the model of radial oscillations (Sect. 2.3) – light blue curves for the second shell at 120 kpc (parameters of the shell are highlighted in bold in Table 1). For parameters of the host galaxy potential, see Sect. 6.1.
