Size-mass relation for the (a) sz and (b) pz samples. Masses for sz galaxies are from the GSWLC catalog (Salim et al. 2016). Masses for pz galaxies are from WH2024. The line styles and symbols have the same meaning as those in Fig. 4. The error bars represent the dispersion, σ, of the log-likelihood. The bottom panels show σ vs. M_★ for (c) sz and (d) pz samples. The gray region in panel b reproduces the result for all the galaxies in the sz sample from panel a.
