Left: epoch 1988 Gaussian measured RVs of the G1376 emission (star) and G1324 absorption (cross) plotted as a function of sidereal orbital phase. RVs are corrected for their corresponding average values. Right: epoch 1988 RVs of G1324 (cross) unshifted in velocity but shifted by 0.5 in sidereal phase, compared to the same measurements for 1992 (square, shifted by −80 km s⁻¹) and 1995 (triangle; shifted by −120 km s⁻¹). The abscissa is the sidereal phase for 1992 and 1995, computed with the parameters listed in Table 4 for the corresponding epoch.
