This equation is satisfied for the values of h/T given in Table I. Thei 

 values of /o/T" are also shown in Fig. 4 as a function of \p. 



3.4 Conversion Factors for Time Deviations 



The conversion factors defined by (2.8) become:

For various values of \p, the factors for ?? = f are given in Table II and 

 in Fig. 5.
