Mirror wavefront error <= 1/16th wave across both diameters

Polish, diffraction edge, figure of revolution, and smoothness all excellent.
	
Arithmetic wavefront error = 1 / 33.7 wave at zone 3 (average both diameters)

Results for individual diameters:
	Reading Diam 1-1: 1 / 16.7 lambda, Max Trans Aberration=0.37
	Reading Diam 1-2: 1 / 16.5 lambda, Max Trans Aberration=0.43
	Reading Diam 2-1: 1 / 18.5 lambda, Max Trans Aberration=0.40
	Reading Diam 2-2: 1 / 18.0 lambda, Max Trans Aberration=0.28
