Table 1: Epochs of the IUE observations with applied radial velocity corrections and continuum ratios used to normalise the spectra (see text). The calculation of the radial velocities is based on Paper III.
Table 2: Journal of TBL observations, with epochs, exposure times and a comparison (O-C) between the measured radial velocities ( $v_{\rm r, O}$ ) and predicted radial velocities ( $v_{\rm r, C}$ ) based on the ephemeris and amplitudes of Paper III. Note that these values correspond reasonably well, provided that a constant difference of $14\pm 1$ km s^-1 for the system velocity is taken into account.
Table 3: Results of the TBL magnetic field measurements. The signal to noise ratio per pixel ( S/N) was measured around 550 nm in the Stokes V spectrum (order 108). The HJD was calculated halfway the four subexposures used for each magnetic measurement. Measurements shown are the effective magnetic field as measured from the Stokes V profiles before and after correcting for the pulsations ( $B_{{\rm eff}}$ and $B_{{\rm corr}}$ respectively) and similarly for the values for N. The last column gives the best-fit velocity shift between the two beams.
