This catalogue lists 1156 stars with magnitude interval 0.~m1~6.~m6, and declination interval -30°~+66°.In compiling the catalogue, corrections and systematic smooth- ing of the right ascensions of stars were carried out on the basis of FK_4 catalogue, but no corrections of the vernal equinox were made, and no attempt was made to establish our own system of proper motions, therefore CTC is a relative catalogue. Observational data spreading ove, 3-5 years were utilized, the total number of star observations reached 76847, so the catalogue has a rather high precision, especially within the declination zone -5°-+56°, having 1043 stars, the precision of position determination in this zone is in general higher than ±4 ms. In this paper, the method of compiling the CTC catalogue is described, and the precision discussed. As the CTC catalogue has been separately published, in this paper only the right ascensions (1975. 0 equinox) which have been determined by three observatories or stations are given for future reference, together with the epoch of observation, number of observation, total standard error, and internal standard error.

The paper gives the, far-field approximations of incompressible sources used in finite elementary solutions. The results obtained can be directly applied to computation. They require much less time for computation than the exact formulas. Errors arising from the use of the far-field approximations are negligible in comparison with those duo to the substitution of the quadrilateral elements for the basic approximation of the body surface. Thus the use of the far-field approximations involves no loss at all in...
