Noise-optimised power spectrum of ϵ Indi. The power spectrum has been oversampled for visual purposes. A clear power excess due to solar-like oscillations can be seen centred just above 5 mHz. The vertical dashed line represents the measured ν_max (see text for details). The inset shows the spectral window, with prominent sidelobes (daily aliases) due to the single-site nature of the observations.
