Maximum wavefront error = 1 / 27.5 wave at zone 1 (measured)
Results for individual sets of readings:
Diameter 1: 1 / 35.0 lamda, Max Trans Abberation=0.14
Diameter 2: 1 / 22.7 lamda, Max Trans Abberation=0.34
Maximum wavefront error <= 1/20th wave on two diameters
Polish, diffraction edge, smoothness all excellent
