Scientific paper

For the 778 stars for which we were able to detect oscillations we fit a power law with a gaussian for the background signal and oscillation signal respectively. The centre of the gaussian is taken as the frequency of maximum oscillation power (numax). The large frequency separations (deltanu) between radial modes with consecutive orders are computed using the autocorrelation of the Fourier spectra, the comb response function and the power spectrum of the power spectrum.
