PERTURBATIONS. 



Applying these secular terms to the corresponding periodic coefficients just preceding, and 

 then multiplying by the sines and cosines of the proper multiples of e, we obtain the following 

 perturbations by means of the Traverse Tables, Tables B: 



FROM TRAVERSE TABLES. TABLE B. 



The perturbations are 



ndz= +0?1954; log (1 +v) 



-0.00032; £/? =+0.00004; 



and 



M = nz = g + ndz = 203 ?2942. 



For an example for the computation of a geocentric position with the aid of M, log (1+v) 

 d log r, and dp, see the example of (179) Klytaemmstra , page 215.
