	Reference parabola: y = -0.0241685 * x**2 + 0.0211851
	passing through (  3.88,  0.00) and (  6.37,  0.00)

Maximum wavefront error = 1 / 22.1 wave at zone 4

Results for individual sets of readings:
	Reading set 1: 1 / 25.1 lamda, Max Trans Abberation=0.44
	Reading set 2: 1 / 18.6 lamda, Max Trans Abberation=0.80

       Polish, diffraction edge, surface smoothness all fine.
