Figure 12 - Deviations from Sphericity"" 



Figure 12a — Huii Number 1, Inside View Looking Forward 



NOTE: Contours are plotted in intervals of 5 mils. Minus 

 contours indicate inward deviations, i.e., -10 indicates distance 

 from center of sphere is 39.630 in. For local geometry in areas 

 marked by Roman Numerals, see Table 1. 



*The surface enclosed by the solid circle shown represents a hemisphere unfolded into 

 flat surface whose radial scale remains constant.
