Deviation between the T_eff (upper panel) and log g (lower panel) obtained by GSP-Phot and the theoretical values of the isochrone models with different degrees of stellar rotation. The green, yellow, and red lines represent, respectively, the deviations from the theoretical isochrones with rotational angular velocities of ω_i = 0.1, 0.5, and 0.9. The error bars denote the degree of dispersion in each color bin.
