I did try to model this in sequential programs and cant seem to get it
because all the gradient index profiles in Zemax seem to be radially
symmetric.

Actually, the current ZEMAX "GRADIENT 4" surface offers just what is needed
to model this problem. I have no idea when that capability was added to
ZEMAX. I found that a linear temperature gradient produces a small amount
of coma; add a quadratic term to the temperature gradient and you get a much
larger amount of astigmatism.
