I usually don't do the analysis with ronchi, but Mel has a great ronchi
program that will show you exactly what the mirror would look like under a
ronchi screen and you may be able to interpolate what you have from a
sphere with what the paraboloid ought to be, possibly showing that a zone
is 5% from a sphere to a paraboloid, allowing you to determine the error.
