Seismic radius as a function of seismic mass for stars identified as RC following Section 4. The maximum log(g) values of the RC for the different YREC models are represented by the diamonds. The colors depict models with different core overshooting values: no overshooting (dark green), 0.1 pressure scale height (cyan), and 0.2 pressure scale height (dark blue). The minimum radius values for the different MIST tracks are shown as black crosses.
