Percentages of S0-like remnants resulting from major and minor mergers hosting different visual ICs at their centres or certain morphological features in their main discs. Panel a: cumulative percentages of lenses an ovals in the major- and minor-merger samples separately. We have distinguished the three kind of lenses according to their vertical shapes, as identified in their edge-on images (spheroidal, lentil-shaped, or flat). All S0-like remnants host a lens or oval component. Panel b: percentages of morphological features detected in the main disc of the S0-like remnants for the major- and minor-merger samples separately. This indicates that major-merger remnants tend to be more resistant to disc instabilities than minor-merger ones. Panel c: the same as in panel (b), but for the ICs. Major-merger S0-like remnants also tend to host a higher number of visual ICs than minor-merger ones. See the corresponding legend in each panel. More information in Table A.5.
