Re: jpeg images

Dear Jacco and All:

   The first image on your website (Si XIV divided by the Mg XI) showing the
   NE jet and west/SW counterjet is very interesting indeed. In the optical
   the NE jet is not symmetrical in terms of abundances - either base to
   tip or even lower side/edge to upper side/edge.
   
   What your image shows (which I don't think is seen in the
   total flux or just Si image) is just how bright the northern edge is
   in this possible counterjet. Of course, we must be careful with the
   term counterjet until we are farther along in the analysis
   (e.g., whether the two jets are aligned with the expansion center and if
   the SW one is, like the NE jet, orientated largely in the sky plane.
   But your image is striking and certainly helps support the counterjet 
   idea.
