R.B. Singh,Bathula Srinagesh,Subhash Anand Thus, . can in principle be determined from the shape of the curve θ(.) without using separations. Consider now two opposite points of the orbit. (. – . = 180°) Then . – . — 180° also holds, as the projection effects are the same, but .2 .1 does not equal 180° except if . 0, or if the two points ar

Koichiro Kinugawa,Teruhiko Imamurad, as it often happens. Differential corrections were not often applied in pre-computer times. Little attention was also given to the development and application of briefer methods of correction (in comparison to the extensive and often unsuccessful efforts to find the solution directly in one step)

Let mA and mB be the apparent magnitudes of the components and mt the total (combined) magnitude of the pair. By definition, . . >0. The formula
