Maximum wavefront error = 1 / 10.6 wave at zone 5 (averaged both diameters)

Polish, diffraction edge excellent; smoothness, figure of revolution fine

Results for individual sets of readings:
	Reading Diam1: 1 / 10.5 lamda, Max Trans Abberation=1.36
	Reading Diam2: 1 / 10.8 lamda, Max Trans Abberation=1.45
