Comments: SN0402 12.5" f/5.9		Date: 8/1/04
   Optical diameter: 12.36"		Substrate: FA Plate
Radius of curvature: 148"		Thickness:  0.70" 
                f/D:  5.99	   	Diffraction disc: 0.000157771

Mirror wavefront error < 1/16th wave PV across both diameters

Polish, diffraction edge, figure of revolution, and smoothness all excellent.
