I/87B LHS Catalogue, 2nd Edition (Luyten 1979)
LHS Catalogue: a catalogue of stars with proper motions exceeding 0.5" annually. Luyten W.J. <University of Minnesota, Minneapolis, September 1979> =1979LHS...C......0L
ADC_Keywords: Proper motions ; Description: The catalogue gathers stars with large proper motions, the large majority coming out of the Bruce Proper Motion Survey (W.J. Luyten). 804 fields in the Palomar Survey have been hand-blinked or processed by an automated blink-machine; 160 low galactic latitude fields could not be handled. There are therefore many less stars with high proper motion south of -33 degrees (limit of the Palomar Survey) compared to the Northern hemisphere. Stars with proper motions larger than 2arcsec/yr are numbered 1 to 100; stars with proper motions between 1 and 2arcsec/yr are numbered 101 to 1000 ; numbers 1001 through 5000 are assigned to stars with proper motions between 0.5 and 1arcsec/yr. The stars which appear to have motions between 0.480 and 0.499arcsec/yr have been assigned numbers larger than 5000. Numbers larger than 6000 refer to Appendix II of the printed publication, containing stars for which at one time or another a value larger than 0.49arcsec/yr was published; these numbers are not listed in the printed version of the catalogue. All proper motions have been reduced to the Palomar-Bruce system. The catalogue supersedes the "Catalogue of Stars with Motions exceeding 0.5" annually" (LFT) published in 1955 (CDS ref. I/54) See also: I/98 : NLTT Catalogue (proper motion exceeding 0.2" annually) I/279 : Revised Luyten Half-Second Catalogue (Bakos+ 2002ApJS..141..187B) File Summary:

Historical Notes: * March 1984: first announced in CDS Inf. Bull. 26 * 16-Mar-1995 (version 'A'): reformatted at CDS, transformed to lower-case, and added notes.dat. Duplicate entry LHS 3224 has been deleted Erroneous BD+04 3561 number for Barnard's star (LHS 57) removed * 15-Jul-1998 (version 'B'): following a message by John Gizis (), two erroneous records (LHS 2297 and 3038) have been corrected.
