Fit to KEPLER model 28 (Lampe et al. 2016), showing the effectiveness of the empirical model power-law plus Gaussian function. The model has a metallicity of 2%, a hydrogen content of 70.48%, and an accretion rate of 8.2% of Eddington, so it is expected to have a strong rp tail. Fiducial errors have been applied to calculate the goodness of fit (gof) with the reduced chi-squared formula. The gof numbers have no meaning in an absolute sense but may be compared with each other.
