Bob,
The edge is high. There is hardly any detectable difference in focus from the 5th to the 6th zone in my ke readings. The edge is still sperical and has hardly moved since I corrected the edge last week. Parabolization had some effect of course.

I'm going to do 1 rotation of the mirror with 1 or 2 long chord stroke MOT per clock position. I just want to see how much it moves the edge. I have .1 microns to move it so I want to be cautious.

Thanks,

Tom P.
