ADC_Keywords: Stars, luminous ; Milky Way ; Spectral types Description: The catalog contains a series of works published in the period 1959 to 1965, resulting from a joint survey of the Hamburg and Warner and Swasey Observatories for early-type stars of high luminosity. This survey was conducted using objective-prism plates taken with the Schmidt telescopes of the Hamburg, Warner and Swasey, and University of Michigan Observatories. The catalog contains all stars of the six source publications in a single file; the notes and remarks published in Volumes II, IV, and VI are included in the separate file "notes.dat". File Summary:

Note on LS, Vol: The LS column is made of a declination zone (a sign and 2 digits), followed by a running number in the zone. Note that a complete LS designation must include the volume number, since the same zone/number combination representing different stars may exist in two or more volumes. In practice, the LS designation is written e.g. "LS II +34 26" for star from volume 2, numbered 26 in zone +34°. Note on m_BD: The note includes e.g. P (primary or preceding), S (secondary), F (following), or remarks (?, 9 = BD and BD+1 stars together). Note on Sp: All characters are in upper case. For uncertain spectral types (enclosed in parentheses) the left parenthesis occurs in byte 20, e.g., it is possible to select all uncertain types by retrieving all stars having a "(" in byte 20. The types are uniform enough to allow a search of byte 21 for all O, B, A,... stars, but the luminosity classes are not uniform. Plus and minus signs occur for their superscript counterparts and the following abbreviations are employed: CE - continuous emission near the Balmer limit LE - line emission, usually ≥ 1 members of the Balmer series if not otherwise specified, observed on the blue plates H - H-alpha observed in emission R - reddened P - peculiar () - enclose uncertain information : - entire spectral type uncertain Exclamation points (!) can occur in the field. The W for Wolf-Rayet types is in byte 21. The entire field is blank when no data are given. Note on Pmag, u_Pmag: The Pmag column contains generally a photographic magnitude, unless the u_Pmag column contains a "m" indicating a visual or photovisual magnitude (Ptv) taken from the Henry Draper Catalogue (Cat. III/135). A 'V' in the u_Pmag column indicates a variable star, and a colon (:) an uncertain magnitude. Note on Remarks: The remarks include slit spectral classifications, mostly from Morgan, Code and Whitford (1955ApJS....2...41M) and Hiltner (1956ApJS....2..389H); Aitken double-star (ADS) identifications; variable-star names; "AGK2" if star occurs in that catalogue (see Cat. I/61) ; number of star included in the list of Brodskaya and Shajn (1958IzKry..20..299B); and miscellaneous short remarks. An "*" indicates a note detailed in the "notes.dat" file.

History: The main part of LS catalogue was originally keypunched at CDS, Strasbourg, as catalogue numbered III/15, around 1972. It was later documented and completed by Wayne H. Warren Jr., at ADC/Goddard in 1982, as catalogue numbered III/76, with the following changes (from document NSSDC/WDC-A-R&S 82-12): "The LSN catalogue was received on magnetic tape from the Centre de Donnees Stellaires, Strasbourg. As received, the single file had a logical record length of 83 bytes. The following modifications and additions were made to the catalogue at the Astronomical Data Center, NASA Goddard Space Flight Center: 1. Preceding zeroes were removed from the LSN number, BD number, and m(pg) fields. 2. LSN number zones from -00 degrees southward were coded 90, 91, .... These were changed to -00, -01, -02, ... to match the real zones. Signs were added to all LSN numbers and declination fields. 3. Uncertain spectral types (surrounded by parentheses) were shifted such that the "(" always occurs in byte 20 of the record. 4. The characters "VAR" in a few mpg fields were changed to "999" so that the field can be read with a numerical format specification if desired. 5. General editing was performed on the remarks field to separate words, star names, etc., to correct punching errors (such as zero in O spectral types, misspellings, etc.), and to add R codes to records having remarks not indicated in the data file. Duplicate stars, indicated by I and II in the first column of volumes III and V) are denoted by VOL I and VOL II in remarks. 6. Commas in the coordinate fields to indicate lower accuracy were changed to seconds of time and arcseconds in right ascension and declination so that they will not interfere with numerical format specifications. 7. All ampersands (&) were converted to plus (+) signs. (They were present due to the creation of the file in an older character coding system.) 8. Bytes 74 to 82 of each record were found to be never used; hence, the asterisks in byte 83 of the original records were moved to byte 77 and the record length was shortened to 77 bytes. 9. The completed file was sorted by increasing right ascension and added to the catalogue as a second file. 10. The remarks published in Volumes II, IV and VI were computerized and added as the third file. " * 07-Dec-2000: standardized documentation added at CDS (Francois Ochsenbein), and two missing stars (volume IV, stars -12 59 and -00 5) were added. The volume number was introduced in the notes, to remove the existing ambiguities. This version of the LS was numbered III/76A. * 26-Aug-2003: the hour of the right ascension of the four stars LS I +63 197-200 have been corrected (from 02h to 03h) Acknowledgements: A large fraction of this documentation was taken from the "Documentation for the Machine-Readable version of Luminous Stars in the Northern Milky Way" (April 1982) by Wayne H. Warren Jr., at ADC/Goddard, document document NSSDC/WDC-A-R&S 82-12.
