Notes. The column in boldface font corresponds to our new reference seismic model for KIC 08626021.

(§)Errors are estimated from the probability distributions of the parameters.

( * )Optimal model found by Giammichele et al. (2018).

( ⋆ )Solution from models constructed with Akima splines (see text).

( † )Solution from models constructed with Fritsch-Carlson splines (see text).

( ‡ )Some models use Δ2 as an alternative way to specify the transition width at log(q2).
