Notes.

^(a)

For the SONG analysis, the best-fit parameters from the photometry and radial velocities were used to set Gaussian priors on T_p, T₁₄, p, b, and K.

^(b)

We find a significant offset between the values for γ derived from the HERMES and SONG data. An analysis of our methods revealed the offset; this offset likely originates from a difference in the spectral templates used in reducing the HERMES and SONG data, but does not influence our results.
