Table 2: Frequencies and amplitudes of the first moment of the Si III 4553 Å line, together with their standard errors. The quoted errors for the frequency are intermediate between the overestimated value given by the frequency resolution, $1/T \sim 6\times 10^{-4}~\ensuremath{{\rm c~d}^{-1}}$ , and the underestimated value given by Period04 for an ideal case free of aliasing and for white uncorrelated noise ( $6\times 10^{-6}, 6\times 10^{-6}$ and $2\times 10^{-5}~\ensuremath{{\rm c~d}^{-1}}$ for f₁, f₂ and f₃, respectively).
