\begin{table*} \caption[ ]{Quantitative parameters measured in the Si
III 455.26 nm line profiles of $\eta$ Cen. The following notation is
used: HJD... heliocentric Julian date of the mid-exposure decreased by
2,400,000, RV... stellar radial velocity measured on the outer wings
of the line (in \kms ), $<v>$... the first line moment (in the
heliocentric wavelength scale; in \kms ), $<v>_c$ the first line
moment (in the heliocentric wavelength scale corrected for the radial
velocity RV; in \kms ), FWHM... full width at half maximum (in \kms ),
LD... difference of central depth of the line with respect to the mean
profile (in units of 10$^{-3}$ $\times$ continuum), EW...  equivalent
width (in units of 0.01 nm), y, b, v, u, c$_1$...  Str\"omgren
photometry interpolated into times of spectral observations (in
mag.).}
