Graphical visualisation of Table 2. The numbers i of the x-axis should be read as model i. From top to bottom: mass, radius, and age of the different models. The dark orange band indicates the final 1σ-interval (cf. Table 3) and the light orange band the precision requirements of PLATO (15% in mass, 1−2% in radius, and 10% in age). The optimal stellar parameters are well within the PLATO precision requirements.
