	Reference parabola: y = -0.0450547 * x**2 + 1.3588
	passing through (  2.56,  0.00) and (  6.97,  0.00)

Maximum wavefront error = 1 / 11.7 wave at zone 4

Results for individual sets of readings:
	Reading set 1: 1 /  8.2 lamda, Max Trans Abberation=1.19
	Reading set 2: 1 / 14.3 lamda, Max Trans Abberation=0.44

       Polish, diffraction edge, surface smoothness all fine.
