Notes. The first two columns are computed from the measurement of the Doppler shift of the centre of the lines in the individual spectra of the primary and the secondary, the next two are the results obtained with the MIDAS (deblend/line) measurement of the centre of the lines and the last two are the semi-amplitudes observed by Linder et al. (2007) for HD 100213.
