Light curves properties as a function of the pulsar-companion separation. Upper panel: integrated synchrotron power over the whole orbit (red points), normalized by the power computed for the isolated pulsar. The total synchrotron power scales as $d_{\mathrm{comp}}^{-0.56}$ (red line). Middle panel: the orbital phase difference between peaks (light blue points) scales as $d_{\mathrm{comp}}^{-0.68}$ (light blue line). We plot the corresponding 1/Γ factors normalized by a factor 0.55, computed before the companion for each run (dark blue crosses). Lower panel: angular offsets of the emitting cone with respect to the pulsar-companion direction (green points) and ratio of the wind drift velocity components V_ϕ/V_r = R_LC/r (green line) given by the monopole analytical solution (Michel 1973).
