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 and 22,395 stars fainter than V=11. Released after the original PPM, the PPM supplemental list was intended to render the PPM complete to magnitude V=7.5.
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 Henry Draper Catalogue (HD) is an astronomical star catalogue published between 1918 and 1924, giving spectroscopic classifications for 225,300 stars; it was later expanded by the Henry Draper Extension (HDE), published between 1925 and 1936, which gave classifications for 46,850 more stars, and by the Henry Draper Extension Charts (HDEC), published from 1937 to 1949 in the form of charts ...
The catalog lists 9,110 objects, of which 9,095 are stars, 11 are novae or supernovae (which were "bright stars" only at the time when they were at their peak), [1] and four are non-stellar objects which are the globular clusters 47 Tucanae (designated HR 95) and NGC 2808 (HR 3671), and the open clusters NGC 2281 (HR 2496) and Messier 67 (HR 3515).
The Michel catalog (MICHEL-Briefmarken-Katalog) is the largest and best-known stamp catalog in the German-speaking world. First published in 1910, it has become an important reference work for philately , with information not available in the English-language Scott catalogue .
One must go to a Michel catalog, for instance, to see them described. The lack of a Scott listing, though, means that most American dealers will refuse to trade in such stamps. Similarly, Scott lists most stamps from countries embargoed by the U.S. government, and in some cases lists them without catalog values. To some extent, this is ...
