Online version of the SAO Catalog was created by the HEASARC in March 2001 based on ADC/CDS Catalog I/131A, which itself is originally derived from a character-coded machine-readable version of the Smithsonian Astrophysical Observatory Star Catalog (SAO, SAO Staff 1966) prepared by T.A. Nagy in 1979, and subsequently modified over the next ...
The SAO catalogue contains this major piece of information not in Draper, the proper motion of the stars, so it is often used when that fact is of importance. The cross-references with the Draper and Durchmusterung catalogue numbers in the latest edition are also useful. Names in the SAO catalogue start with the letters SAO, followed by a number.

In contrast to the PPM, these older catalogs are based on (1) the now obsolete FK4 system of positions and proper motions, and (2) only two position measures per star. [2] While the SAO catalog is more or less complete to V=9, with 4,503 stars fainter than V=10, the PPM catalog is fairly complete to V=9.5, with 102,672 stars fainter than V=10 ...
The Catalog of Stellar Identifications (CSI) is a star catalog which was constructed to facilitate cross-referencing between different star catalogs. It contains designations and basic data for, as of 1983, approximately 440,000 stars, and was created by merging the Smithsonian Astrophysical Observatory Star Catalog, the Henry Draper Catalogue, the AGK2/3, the Cape Photographic Catalogue, the ...
The catalogue, published in three parts, was accompanied by charts plotting the positions of the stars, [1] and was the basis for the Astronomische Gesellschaft Katalog (AGK) and Smithsonian Astrophysical Observatory Star Catalog (SAO) catalogues of the 20th century.
