The evidence presented here demonstrates the reality of long period brightness oscillations in the solar limb darkening function. This extension of the FFTD, the simultaneous application of multiple edge definitions, provides another test for establishing the reality of long period solar oscillations. Additional information, namely the signature, characterizes the signal measured, and can be used to enhance detection of these faint and complex signals. In essence, brightness oscillations can be detected without relying on the broadband statistics of spectra. This is essential for study of small bands in highly resolved spectra. The signature information also affords a vehicle for comparison to pulsation theory, another step toward seismology.
