Abstract

An updated, corrected, and extended machine-readable version of The Henry Draper Catalogue (HD, Cannon & Pickering 1918-1924) is available with documentation from the Astronomical Data Center (ADC) as of April 1989. Published and unpublished errors discovered in the previous version have been corrected; letters indicating supplemental stars in the BD have been moved to a new byte to distinguish them from double-star components; and the machine-readable portion of The Henry Draper Extension (HDE) (HA 100; Cannon 1925-1936) has been converted to the same format as the main catalog with additional data added as necessary. The catalog lists HD numbers, Durchmusterung numbers, positions for equinox B1900, photovisual and photographic magnitudes, spectral types, codes for the intensity of the spectra used, and remarks.
