Table 8.5. Typical and extreme values of range errors for targets beyond the atmosphere 



The first term on the right-hand side of (8.19) is the "velocity" or 

 "refractivity" error, ARn', the last two terms represent the geometric 

 range error, ARg, which is the difference in length between the straight 

 path, Ro, and the curved ray path, Rg. Table 8.5 gives some typical and 

 extreme values of range errors ray traced for observed A'^ profiles.
