Results of GP regression and amplitude spectrum fitting for the noise-enhanced light curves of HD 112244 (TIC 406050497) and HD 96715 (TIC 306491594), which are typical yellow and blue subgroup members, are shown in the left and right columns, respectively. From top to bottom, increasingly larger amounts of white noise has been added. The blue and green shaded regions denote the 94% confidence interval for ν_char for each method. The ν_char values from the GP regression are more consistent, on average, than those from fitting the amplitude spectrum.
