Double Stars with Common Proper Motion
Published online by Cambridge University Press: 25 July 2018
Extract
The proper Motion Survey with the 48-in Schmidt telescope has now progressed far enough such that we may begin to make some meaningful statistical discussions of the results obtained. Altogether 135 regions have been blinked - one seventh of the total - and in particular all fifty plates covering the area of the North Polar Cap, north of declination +69 (1855) have been blinked and completely measured.
