Result of CubeFit on the NE mosaic for both H2 lines. A black curve on the flux map delineates the amplitude threshold (see text). This region is masked out in the other maps. The four maps are, from top left to bottom right: H2 λ2.12 µm line flux 
, flux ratio between the two lines 
, common intrinsic linewidth 
, and common intrinsic radial velocity shift 
.
