Histograms of the number of good fits (solid line) as a function of frequency for the periodogram, the sine multitaper spectrum, and the corresponding denoised multitaper spectrum of ﹩\ell =30﹩. Each bin contains the modes of a single n‐value summed over all m. The dotted line represents the total number of fits including the bad ones, and the dashed line represents the good fits from the panel above.
