folder and the click the thumbnail.

here is a scanned page of my focault test.  I am sure there are things I
need to differently with this test.  For instance, my knife edge is not
perfectly strait up and down on both axis.

The Pictures on the left are outside of the ROC.

The picture on the top left is ROC (As best as I can tell.  It is where the
shadow seems to just pop up over the whole surface at once.)

If you can not read my scribbles, they basically represent what I saw in mm
inside or outside of ROC.  If I were to rotate the mirror, the zones that
are reflected here stay consistent.

Can you tell me what figuring stroke I need to undertake to resolve this issue?

When migrating to the outside of ROC further, the "hill" in the
middle of the mirror shows up to be spherical just further out than the
regular ROC. I am completely new at this so I am actually using the outside
of my mirror as the reference sphere.

I hope my scribbles give you a basic understanding of what is going on.

Thanks for your help,
Byron
