Re: jpeg images (fwd)

Hi all,

Just to add some on the theory end.  We are running a large suite of
3-dimensional explosion calculations with detailed abundance calculations.
Once we get the first set finished, I'll put them on the web.  But let me
say a few words of caution.  If the asymmetry is in the explosion, and not
the environment (e.g. the binary+windswept media) around the star prior to
collapse, then my money is on the iron having the biggest asymmetry.

My intuition may be wrong here, I'll know more when we've finished this
suite of simulations and after we get a better handle on the progenitor,
but this looks a lot more like a binary affected environmnent to me.
