Effective temperature from J-PLUS photometry, $T_{\text{eff}}^{\text{J-PLUS}}$, as a function of the value derived by Coutu et al. (2019), $T_{\text{eff}}^{\text{C}19}$ (left panel). The dashed black line marks the one-to-one relation and the dotted red line a 4% overestimation from J-PLUS with respect to the temperature from Coutu et al. (2019). Right panel: relative difference between effective temperatures as a function of $T_{\text{eff}}^{\text{C}19}$. The dashed black line marks a zero difference and the dotted red line a 4% overestimation. The red area encloses 68% of the points and it is equivalent to a 3% dispersion.
