Aditya,

I am sorry, I have misplaced your Radius of Curvature value.  I can't run
Sixtests without it.  This should be a measurement to about 1 mm accuracy
of the distance from the center of your mirror to the knife edge of your
tester when the knife edge is positioned to null the innermost zone.  If
using a fixed source tester, I need either both the distance to the
pinhole/slit and the disatnce to the knife edge, or the average of the two
distances.

Thanks.
