Astrophysical parameters of the P1 targets within the LOPN1 (left panels) and LOPS1 (right panels) provisional fields. Top panels: Distribution of P1 targets on the (T_eff, R_⋆) plane; stars are classified into five distinct groups representing main-sequence K-type dwarfs (dK), G dwarfs (dG), F dwarfs (dF), subgiants at T_eff < 5500 K (sg_cool), and T_eff > 5500 K (sg_hot). The labels show their relative occurrence. The gray line in both panels marks an arbitrary boundary between main-sequence and evolved stars (see text). Bottom panels: Histograms of the distribution in distance of the same subgroups. The best-fit lognormal distribution is also over-plotted with a continuous line.
