The corrections <^ loq a, have been added to take aoconnt of 

 eventual corrections A, to the masses and to J and K. We also put

Then we have

For the coefficients Ai of tlie first term of tiie eqnations (2) 

 we find 



The second term can be neglected for the satellites III and IV. 

 For I and II it contributes — 2 and — 5 respectively to the eighth 

 decimal place of e,. 



The third term gives
