Relative offsets of the peak of the emission of LS 5039 during five consecutive days with respect to the average position. For straightforward comparison, we plot the opposite value of the inverse astrometry. The run label is displayed close to each direct measure. The size of the binary system is indicated by the small orbit in the corner, which is plotted face-on and with an arbitrary orientation. The displacements and uncertainties are shown in Table 2.
