Doppler tomography of V834 Cen. Same layout as Fig. 2. The model velocity profile overlay shown in both tomograms is based on the model used by Potter et al. (2004) with an inclination angle of 50°, a primary mass of 0.85 M_⊙, a mass ratio q = 0.154 and an orbital period of 0.070497518 d (~101.5 min; Schwope et al. 1993). The Roche lobes of the primary (dashed line) and the secondary (solid line) as well as a single particle ballistic trajectory from the L₁ point up to 45° in azimuth around the primary (solid line), are included in the overlay. Magnetic dipole trajectories are calculated from 5° to 45° in azimuth around the primary (thin dotted lines) at 10° intervals using a dipolar axis azimuth and co-latitude of ~36° and ~20°(Potter et al. 2004), respectively. The first of the dipole connections (small circles) are at (360 km s^-1, 135°) and the first dipole trajectory starts at (150 km s^-1, 162°). Consecutive trajectories start at locations with progressively higher velocities and polar angles.
