IV/12               SAO-HD-GC-DM Cross Index (ADC 1983)  (Roman+ 1983)

SAO-HD-GC-DM Cross Index Roman N.G., Warren Jr. W.H., Schofield Jr. N.J. <Astronomical Data Center (1983)>
ADC_Keywords: Cross identifications Description: The catalog is an updated, corrected, and extended version of a table of correspondences originally prepared by Morin (1973). The individual data corrections, additions, and changes included in the new version number 11398, with 8600 data records having at least one change. In addition to the correction of all errors found since preparation of the original catalog, most of which resulted from misidentifications and omissions of components in multiple-star systems and missing Durchmusterung numbers (the common identifier) in the SAO Catalog, component identifications from the Index Catalogue of Visual Double Stars (IDS) have been appended to all multiple SAO stars having the same DM numbers, and lowercase identifications for supplemental (footnoted) BD stars have been added. Stars deleted (duplicate entries) in the SAO Catalog have been appended with a "D" and their data removed, although the records have been kept (with SAO number only) in order not to change the number of SAO stars. The data include SAO number, HD number, HD multiplicity code, GC number, DM identification code (BD, CD, CP), and number. There are fewer objects than records because of the deleted entries appended with a "D" as described above (35 stars deleted). File Summary:

Note on DM: the Durchmusterung identification is made of DMcode in bytes 20-21 ("BD", "CD" or "CP") DMzone in bytes 30-32 (zone in degrees) DMnumb in bytes 33-36 (running number in zone) DMsupp in byte 32 ("a" or "b" for additional stars) Note on m_HD: the multiplicity code contains: '0' Single star, or companion > 0.3 mag (visual) fainter than the primary to which the entry refers. '1' Brighter component with a companion ≤ 0.3 mag fainter. '2' Fainter component with a companion ≤ 0.3 mag brighter. '9' The SAO Catalog entry refers to two consecutive HD numbers, the lower of which is given.
Historical Notes: See the documentation, either in LaTex (doc.tex), or in plain ascii (adc.doc), section 3. The catalogue distributed on the "Selected Astronomical Catalogs" Vol. 1 CD-ROM (1992, Astronomical Data Center, NASA Greenbelt), directory /crossid/saohddm, contained two more data files not included here: the index sorted by right ascension and declination, and by HD numbers.
