Left panel: comparison between components 1 (contours) and 2 (gray scale). The location of the slices, labeled as a, b, and c, are sketched by the dotted lines. The cross at the center indicates the position of WR 16. Right panels: position-velocity maps obtained for strips a, b, and c. Contour levels start at 1.9 K and the contour spacing is 1.4 K. The loci of both components are indicated by the black arrows.
