Tyrone,

I'm assuming that these images were taken inside of radius. The lines seem
fuzzy enough to me for this to be so.  If so, then your mirror is fairly
spherical and, at least today, has a Wildly Erupting Deformation, or WED,
at its edge. ;)

1/3 W TOT, but leave some of the up edge.  In my opinion figuring is easier
if it's started with an up edge.

Don't worry overly about the surface "imperfections" you see at radius.
They will be polished away while you figure.
