		Reference parabola: y = -0.00105908 * x**2 + 0
		passing through (  0.00,  0.00) and (  4.41,  0.00)

Maximum wavefront error <= 1/20th wave across both diameters

Polish, diffraction edge, figure of revolution all excellent; smoothness very fine.
	
Arithmetic wavefront error = 1 / 32.9 wave at zone 2 (average both diameters)
	Results for individual diameters:
		Reading Diam1: 1 / 29.0 lambda, Max Trans Aberration=0.24
		Reading Diam2: 1 / 28.6 lambda, Max Trans Aberration=0.24
