Systematic Errors in the Photographic Positions of Double Stars at the Sproul Observatory
Published online by Cambridge University Press: 25 July 2018
Extract
The long range program of the Sproul Observatory initiated in 1937 by Peter van de Kamp has been primarily devoted to a detailed astrometric study of the positions of nearby stars from photographs taken with the 24-in. refractor. The accumulation of plates over a long time interval provides the opportunity for finding perturbations of small amplitude leading to the discovery of unseen companions.
