Beginning of ReadMe : I/130 LDS Catalogue: Doubles with Common Proper Motion (Luyten 1940-87) ================================================================================ The LDS Catalogue: Double Stars with Common Proper Motion Luyten W.J. <Publ. Astr. Obs. Univ. Minnesota III, part 3, 35; Proper motion survey with the 48-inch Schmidt Telescope, XXI, XXV, XIX, XL, L, LXIV, LV, LXXI, Univ. Minnes. (1940-1987)> ================================================================================ ADC_Keywords: Proper motions ; Stars, double and multiple Description: This catalogue contains all double stars with common proper motion discovered by Luyten since 1940 up to 1987 (references below). When Luyten had noticed that an entry was duplicated (ref. 8 and 9), only the former LDS number was kept in the data file but with the data given for the latter. The unique exception is LDS 6166, which is a duplicate of LDS 5662, but with an additional component. The systems classified as optical by Luyten were also rejected from the main data files. All the rejected data were put together in a separate file. All coordinates are for the equinox 1950; when the original publication gave another equinox (this is the case for ref. 1), the 1950-coordinates were calculated. The catalogue contains all the systems, sorted by increasing LDS numbers. Duplicate entries and optical systems listed by Luyten were rejected. The catalogue contains 6121 systems, including 87 triple and 1 quadruple systems. The number of records is thus 6210, since each triple system occupies 2 records and the quadruple system 3.
