Left: VLT/CRIRES high-resolution (R = 100 000) Brγ spectrum (top panel) and centroid displacements of the Brγ-emitting region (lower panels) for MWC297. The position angle of each slit is shown to the left of each phase panel. Right: derived 2D photocenter displacement vectors of the Brγ + continuum emission for MWC297. The black line shows the position angle of the disk major axis determined from our AMBER LR observations.
