Absolute RV estimates from the multi-epoch observations of our sample as a function of Heliocentric Julian Date (HJD). Black points indicate the LR02 measurements and red stars show the LR03 measurements; there is an excellent agreement between the two settings (see Table 2 for details). Each panel has the same vertical scale to highlight the amplitude of the observed variations. The fibre configuration (Fields A-I) in which each target was observed is also indicated. Corrections for instrumental variation have been implemented for 13 of the targets (excl. VFTS 289, 341, 852, 2028; see text for details).
