Results of the photometric analysis for the star 0319−7254. (a): Corner plot (Foreman-Mackey 2016) showing the correlations among the measured physical parameters. The colored lines respectively mark the estimated parameters obtained from the spectral analysis (blue: Koester models; orange: Tremblay models) or other works (green: the Gentile Fusillo et al. 2021 parameters as well as the parallax-based distance and the interstellar extinction from the 3D maps). (b): The best-fitting SED (black line) is compared to the Gaia BP/RP spectrum (cyan). The gray shaded line represents fifty random draws from the parameters distributions (using the Koester models). The bottom-panel shows the residuals between the model and the observed data.
