LOSVD map of the simulated shell structure 2.2 Gyr after the decay of the cannibalized galaxy (middle panel in Fig. 10). Light blue curves show locations of the maxima according to the model of radial oscillations (Sect. 2.3) for shell radius r_s, corresponding serial number n, and the known potential of the host galaxy (Sect. 6.1). Orange curves are derived from the approximative maximal LOS velocities (Sect. 5, point 3) given by Eq. (17) for r_s, v_s,model, and v_c,model. Parameters of the shells are shown in Table 2. Black lines mark the location at 0.9r_s for each shell. The LOSVD for these locations are shown in Fig. 12. The map includes only stars originally belonging to the cannibalized galaxy.
