Left and middle panels: V vs. (B − V) and Gaia G vs. (G_BP − G_RP) colour-magnitude diagrams (CMDs). Right panel: Kiel diagram, log g vs. T_eff. Star BPM 3066 is indicated by the filled star. In the right panel, the orange star is for the parameters we adopt here, while the blue one is for the GALAH BSTEP parameters. In all panels, two PARSEC isochrones of metallicity and ages ([M/H], Age) = (−0.71, 11.7) and (−1.26, 13.0) are shown in blue and orange, respectively.
