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).

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.
