Wolf catalogues pioneered the domain: Ross, Frank Elmore, New Proper Motion Stars, eight successive lists, The Astronomical Journal, Vol. 36 to 48, 1925–1939 Wolf, Max, "Katalog von 1053 stärker bewegten Fixsternen", Veröff. d. Badischen Sternwarte zu Heidelberg (Königstuhl), Bd. 7, No. 10, 1919; and numerous lists in Astronomische Nachrichten, 209 to 236, 1919–1929 Willem Jacob Luyten later produced a series of catalogues: L – Luyten, Proper motion stars and White dwarfs Luyten, W. J., Proper Motion Survey with the forty-eight inch Schmidt Telescope, University of Minnesota, 1941 (General Catalogue of the Bruce Proper-Motion Survey) LFT – Luyten Five-Tenths catalogue Luyten, W. J., A Catalog of 1849 Stars with Proper Motion exceeding 0.5" annually, Lund Press, Minneapolis (Mn), 1955 () LHS – Luyten Half-Second catalogue Luyten, W. J., Catalogue of stars with proper motions exceeding 0"5 annually, University of Minnesota, 1979 () LTT – Luyten Two-Tenths catalogue Luyten, W. J. Luyten's Two Tenths. A catalogue of 9867 stars in the Southern Hemisphere with proper motions exceeding 0".2 annually, Minneapolis, 1957; A catalogue of 7127 stars in the Northern Hemisphere with proper motions exceeding 0".2 annually``, Minneapolis, 1961; also supplements 1961–1962. () NLTT – New Luyten Two-Tenths catalogue Luyten, W. J., New Luyten Catalogue of stars with proper motions larger than two tenths of an arcsecond (NLTT), Univ. of Minnesota, 1979, supplement 1980 () LPM – Luyten Proper-Motion catalogue Luyten, W. J., Proper Motion Survey with the 48 inch Schmidt Telescope, University of Minnesota, 1963–1981 LP numbers: L in zones −45 to −89 deg.; LP in zones +89 to −44 deg. Around the same time period, Henry Lee Giclas worked on a similar series of catalogues: Giclas, H. L., et al., Lowell Proper Motion Survey, Lowell Observatory Bulletin, 1971–1979 () Struve Double Star Catalog Friedrich Georg Wilhelm von Struve discovered a very large number of double stars and in 1827 published his double star catalogue Catalogus novus stellarum duplicium. For example, binary star 61 Cygni is designated "Struve 2758" or "STF 2758". Stars of his catalogue are sometimes indicated by the Greek letter sigma, Σ. Thus, 61 Cygni is also designated as Σ2758. uvby98 The ubvyβ Photoelectric Photometric Catalogue is a compilation of previously published photometric data. Published in 1998, the catalogue includes 63,316 stars surveyed through 1996. ZC catalogue The Robertson's Zodiacal Catalogue, collected by the astronomer James Robertson, is a catalogue of 3539 zodiacal stars brighter than 9th magnitude. It
