Notes. The frequencies, linewidth and height are fitted parameters, the height-to-background ratio (H/B) is measured as the observed height of the oscillation mode in the power spectrum over the fitted background. The amplitudes and ``unbiased'' lifetimes are derived from the fitted parameters as described in the text.
