Result of CubeFit on the NE mosaic for the Brγ line. A black curve on the flux map delineates the amplitude threshold (see text). This region is masked out in the other maps. The three maps are, from left to right: line flux (F_Brγ), intrinsic width (σ_Brγ), and intrinsic radial velocity shift (υ_Brγ)·features can be seen consistently in all parameter maps (clearly in the linewidth, flux and velocity maps, less clearly in the flux ratio map).
