3135A III/135A Henry Draper Catalogue and Extension A J Cannon E C Pickering Harv. Ann. 91-100 ??? ??? 1918-1924 1924hdhc.bookQ....C Spectral types Surveys 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 Published and unpublished errors discovered in the previous version have been corrected; letters indicating supplemental stars in the BD have been moved to a new byte to distinguish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.

HD Henry Draper Catalog (HD) number number= According to W. H. Warren Jr., 194629 is identical to 194648 and the latter should be deleted. --- DM Durchmusterung identification number=1 the DM number is composed of: Bytes 7-8: catalog ID, 'BD', 'CD', 'CP', or 'AG' for AGK1 stars (zones +50 to +59) not in the BD Bytes 9-16: Durchmusterung catalog number, SZZNNNNN. For AG zones, the ZZ field contains the lowest declination zone in the appropriate catalog (50 or 55) Byte 17: BD supplement letter (catalogue <I/71> by Warren and Kress) Byte 18: DM component identification --- RAh Hours RA, equinox B1900, epoch 1900.0 number= According to W.
