Evolution of the LOSVD near the shell edge for the second shell at r_s = 120 kpc (parameters of the shell are highlighted in bold in Table 1) for the projected radius 116, 117, 118, and 119 kpc in the framework of the model of radial oscillations (Sect. 2.3). In this model, the current turning points of the shell particles are at r_TP = 117.9 kpc. Beyond this radius, the inner maxima disappear. Profiles do not include stars of the host galaxy, which are not part of the shell system and are normalized so that the total flux equals one. For parameters of the host galaxy potential, see Sect. 6.1.
