Ooooh, I wish I could say better, but?!?!!  Nasty looking stuff here, not
for the faint of heart. ..

I find it looks the worst when it comes off of the lap.  After an hour or
so it is much nicer,  but the astigmatism is still there.  After looking
at the post by Dale Eason, "warming the edge of a mirror .."  I am not
surprised that I see this coming off of the lap.

The pictures, from left to right, are Outside ROC,  Outside ROC,  Near
ROC,  Inside ROC.  Big hump in the middle.  This will be a good test of
the adage

"No matter what you polish into a mirror, you can polish it out"

Or something like that.
