Upper panel: position of HIP 21743 on the HR diagram (black dot). The two closest evolutionary models from Salasnich et al. (2000) are overplotted. The red solid line corresponds to a 2.5 M_⊙ RGB model, while the blue dashed line to a 2.0 M_⊙ HB model. Both tracks have a metallicity of Z = 0.008. Lower panel: same as the upper plot, but this time the masses of the models are 1.9 M_⊙ for an RGB star and 1.5 M_⊙ for a HB giant. The position of HIP 68333 is also shown.
