ν versus $\sqrt{\text{Δ}v}$ diagram for KIC 12066947 obtained from the analysis of all available data. Magenta squares indicate modes with “jumps” in the radial order n, with Δ_kn of 2, 3, represented by colored lines starting with orange. Red squares indicate modes with Δ_kn = 1 or corrected by a factor of 1/ $\sqrt{{\text{Δ}}_{k}n}$, while yellow arrows indicate when this correction was applied. Open black points were discarded. The solid blue line represents the first iteration, and the purple dashed line indicates the inclination after convergence. The intercept of the dashed line with the 0.0 line estimates the average rotation frequency, and the slope measures P₀.
