Fits for circular velocity v_c and shell velocity v_s using the approximative LOSVD (Sect. 5, point 2) given by Eq. (15) for four shells (r_s indicated in bottom right corner of each plot) in the simulation 2.2 Gyr after the decay of the cannibalized galaxy. The best fit is the purple curve, and its parameters are shown in Tables 3 and 4 in the columns labeled v_c,fit and v_s,fit. The green crosses mark the measured maxima in the LOSVD, and the light blue curves show the locations of the theoretical maxima derived from the host galaxy potential according to the model of radial oscillations (Sect. 2.3). Note that the values of v_c and v_s used in the approximative LOSVD for the purple line were obtained by fitting the parameters to the simulated data, whereas in Figs. 7, 8, and 12, the values are known from the model of the host galaxy potential.
