VII/220A  Barnard's Catalogue of 349 Dark Objects in the Sky (Barnard, 1927)

Barnard's Catalogue of 349 Dark Objects in the Sky Barnard E.E. <A Photographic Atlas of Selected Regions of the Milky Way, by Barnard E. E., ed. Frost E.B. and Calvert M.R., Carnegie Institution of Washington (1927)> =1927cdos.book.....B =1927Barn..C......0B
ADC_Keywords: Nebulae, dark ; Nonstellar objects Keywords: Dark objects ; Barnard objects Description: This catalogue was created based on the original published catalogue by Barnard E.E., 1927, Carnegie Institution of Washington, "A photographic Atlas of selected regions of the Milky Way". The catalogue contains positions of 349 Barnard Objects. The objects with numbers from 1 to 175 are classified in the first Barnard catalogue (1919ApJ....49....1B); three of the objects in that list have been omitted here (Nos 52, 131a, and 172) because these objects had been listed twice. The objects from Barnard's second list are numbered from 201 to 370 -- there are therefore no objects having the numbers from 176 to 200. Their positions were determined by Miss Calvert. The epoch for all positions in the original published catalogue was 1875.0. Positions for both 1875.0 and 2000.0, the diameters and the notes are included in this machine-readable catalogue.

Historical Notes: * 25-Jun-1999: This catalogue was created by Junko Takahashi and Masatoshi Ohishi at the Astronomical Data Analysis Center, National Astronomical Observatory of Japan, based on the original published catalogue by Barnard E.E., 1927, Carnegie Institution of Washington, "A photographic Atlas of selected regions of the Milky Way." * 24-Jan-2001: The diameters and notes were kindly supplied by Bill Gray from the Pluto project () * 30-Jun-2008: Thanks to Mati Morel, 6 position errors in J2000 positions were corrected for the pairs B67/67a, B83/83a, and B117/B117a Acknowledgments: Takahashi and Ohishi are grateful to Dr. Mitsuru Soma and Prof. Shiro Nishimura for their codes for the coordinate conversion. They also wish to thank all members at the Astronomical Data Center, National Astronomical Observatory of Japan for their cooperation.
