Mass-size distribution of the F3D ETGs (circles) and LTGs (crosses). Orange, green, and light-green symbols represent the ancient, intermediate, and recent infallers, respectively, according to the analysis of the PPS diagram shown in Fig. 6. Galaxies with low (black open triangles) and high star formation (black open circles) are also shown. The slow rotators (SRs) are marked with open black squares. The critical mass, defined by Cappellari (2013), is marked by the black dashed line. For reference, the blue dash-dotted line and the solid red line indicate the upper limit of the spiral galaxies and the lower limit of the ETGs from ATLAS3D sample (Cappellari et al. 2013).
