No. 8.1 MINOR PLANETS— LEUSCHNER, GLANCY, LEVY. 63 



With these tables wo compute terms of the first order in the mass in Hansen's differential 

 equations for the function W and the perturbation in the third coordinate. See Z 7, eq. (33) 

 and Z 8, eq. (39). The first order parts of the equations are expressed in Z 41, eqs. (82), (83), 

 in the form of trigonometric series, in which the coefficients are computed from the formulae 

 given in B 67. These coefficients comprise Tables VIII-XIVw^ (cf. Z, 42-48). 



Table XV (cf. Z 50, eq. (88)) is an auxiliary table of the same type of construction, which 

 is employed in the computation of terms of the second order in the mass in the differential 

 equation for W (cf . Z 53) .
