\caption{Amplitudes (in km~s$^{-1}$) of the frequencies $f_{\rm
rot}\in[0.22;0.28]$~\cd, $f_1 = 4.99922$~\cd\ and $2f_1$ for the {\it EW} ({\it top});
amplitudes (in km~s$^{-1}$) of $f_1$, $f_2, f_3$ and $2f_1$ for $\langle v\rangle$ ({\it bottom})
of the \si\ 4552.654~\AA\ ({\it left}) and \si\ 4567.872~\AA\ ({\it right}) line of \ke,
calculated from the original observed spectra and from the disentangled
spectra. The last column denotes the total variance reduction (f.v.) derived
from the least-squares fits to the data with the considered frequencies.}
