(. – . = 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

Correcting an Orbit,d, 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)

To the present-day orbit investigator, 150 yr old measurements still have far more interest than a mere historical, and so the yellowed folio pages o
