The database below includes 22 stars, all those brighter than apparent magnitude 1.50. These are commonly known as first magnitude stars. The following data is included:
Origins of names have been taken mostly from Star Names: Their Lore and Meaning, by Allen, but also from Burnham's Celestial Handbook, by Burnham.
Bayer denominations, Flamsteed denominations and catalog numbers have been checked against Sky Catalogue 2000.0 (Vol. 1) by Hirshfeld and Sinnott, the Fifth Fundamental Katalog (FK5), by , and the HIPPARCOS Input Catalogue.
Duplicity information has been checked from among various sources, including Sky Catalogue 2000.0, by Hirshfeld and Sinnott, Burnham's Celestial Handbook, by Burnham, and the HIPPARCOS Input Catalogue.
Orbital Elements for Sirius, Rigil Kentaurus, Capella, Procyon, Acrux and Spica have been taken from Sky Catalogue 2000.0 (Vol. 2), by Hirshfeld and Sinnott.
Equatorial Coordinates (J2000.0) are taken from the Fifth Fundamental Katalog (FK5) by.
Galactic Coordinates: Taken from the 5th edition of the Bright Star Catalog, by Hoffleit.
Annual Proper Motion Components: Taken from the Fifth Fundamental Katalog (FK5) by.
Annual Proper Motion Vector: These have been derived from the annual proper motion components given in the Fifth Fundamental Katalog (FK5) by.
Trigonometric Parallax: Taken from HIPPARCOS data.
Distance: These have been derived from the trigonometric parallax values given in the HIPPARCOS database.
