Typical normalized UVES spectrum plotted over the RVS spectral window. The calcium IR triplet at 8498, 8552, and 8662 angstroms for VZ Pup at ϕ = 0.91 is presented. In the following, the spectral line profiles are plotted over the [−200,+200] km s−1 velocity range, represented by vertical strips around each line.
