Fig. 3
Top: shift in velocity obtained from a cross-correlation of the P Cygni profile between the spectrum at the position of the star and each individual spectra in the field, for exposure 1. Color scale is km s-1. The continuum emission center is marked as a black cross. The physical orientation is also given. Bottom: error in the shift also in km s-1.
