Maximum wavefront error = 1 / 18.0 wave at zone 4 (measured, average)

Mirror wavefront error <= 1/15th wave across both diameters

Polish, diffraction edge, figure of revolution all excellent; surface smoothness very good

Results for individual sets of readings:
	Reading Diam 1: 1 / 17.6 lamda, Max Trans Abberation=0.74
	Reading Diam 2: 1 / 15.8 lamda, Max Trans Abberation=0.60
