Evaluation of frequency divisions and ranges, and of frequency estimates and uncertainties, in a close-up view of the standard-resolution ASEF from GLOBAL for the MS star KIC 12069424. Top panel: frequency divisions d_a, b (blue-tone shading) computed from three local maxima ν_i (vertical dashed lines). Middle panel: frequency ranges r_a, b (orange-tone shading) with overlaid the frequencies ν_f, i estimated from the sampling (vertical dotted lines). Bottom panel: stellar PSD, with overlaid the frequencies ν_f, i (red bullets and vertical dotted lines) and corresponding 1-σ uncertainties σ_f, i.
