Distribution of frequency uncertainties δν_{ℓ = 1, max} for the sample of P1P2 stars with expected positive seismic detection. The color code corresponds to different mass samples as indicated in the top right panel. The top panels correspond to the frequency uncertainties computed with Eq. (20) for observation lengths of 730 days (top-left panel) and 90 days (top-right panel). The bottom panels show the frequency uncertainties distribution when one takes into account the scatter in the relation obtained with Eq. (20) (left panel) or the uncertainties in the mode linewidths at low effective temperature width, as per Appendix D (right panel).
