	Reference parabola: y = 0.00255528 * x**2 + 0
	passing through (  0.00,  0.00) and (  4.66,  0.00)

Maximum wavefront error = 1 / 21.0 wave at zone 2

Results for individual sets of readings:
	Reading set 1: 1 / 16.9 lamda, Max Trans Abberation=0.45
	Reading set 2: 1 / 18.4 lamda, Max Trans Abberation=0.45
	Reading set 3: 1 / 17.1 lamda, Max Trans Abberation=0.49
	Reading set 4: 1 / 14.9 lamda, Max Trans Abberation=0.39

       Polish, diffraction edge, surface smoothness all excellent.
