Top: Inner part of the H₂ emission. Contours start at 10 counts per pixel increasing by a factor of two. The dashed lines indicate the cone used to extract the radial dependence of the count rate. Bottom: Deconvolved H₂ image. The magenta lines indicate the region containing 68% and 90% (outer lines) of the [S ii] emission in the velocity range +25 to –120 km s^-1 perpendicular to the jet axis.
