Velocity dispersion (σ_LOS) plotted against M_⋆ for FS90 110 (large diamond) and FS90 192 (large pentagon), alongside a sample of cEs and massive compact galaxies from the literature. The symbol coding follows that of Fig. 5, and the framed symbols depict cEs with mean ages above 10 Gyr. The solid lines represent the scaling relation for quiescent galaxies from Zahid et al. (2016). The dashed lines show the function fitted to these cEs, while the dotted ones correspond to cEs younger than 10 Gyr.
