Figure 16. The "1x1°" geoid is compared to the astrogeodetic profiles of Rice along 35°N and 

 Fisher et al . (1967) along 100°W. The "1x1°" geoid is referred to an ellipsoid 

 of flattening 1/298.25 by using graph in Figure 11. For the astrogeodetic geoids 

 the transformations given by Strange et al. (1971) and Gaposchkin and Lambeck 

 (1971) were utilized. The "G and L" geoid profile atlOO'W referred to an ellipsoid 

 of flattening 1/298.25 is also shown.
