| Abstract: | Rotational enhancement of the sensitivity of whole-disk Doppler observations of solar oscillations may permit the measurement of five-minute modes with l = 4. We estimate from superposed power spectra of artificial solar data that there might be identifiable power lying above the noise in the data acquired by Pallé et al. (1986), which could provide confirmation of the rotational splitting measured by Duvall and Harvey (1984). |
