VII/21              Catalogue of Reflection Nebulae  (Van den Bergh, 1966)

Catalogue of Reflection Nebulae Van den Bergh S. <Astron. J. 71, 990 (1966)> =1966AJ.....71..990V
ADC_Keywords: Nebulae Description: A catalogue is given of all BD and CD stars north of -33deg which are surrounded by reflection nebulosity visible on both the blue and red prints of the Palomar Sky Survey. The nearer reflection nebulae lie predominantly along Gould's Belt, whereas the more distant ones are concentrated to the galactic plane. The data outline 13 associations of reflection nebulae, some of which coincide with known OB or T associations. Attention is drawn to the fact that most reflection nebulae are illuminated by the integrated light of the Milky Way. The integrated radiation will be more intense above and below the galactic plane then in the galactic plane where the nuclear bulge of the Galaxy and most of the disk are obscured by interstellar absorption.

Note (1): a 159th reflection nebula corresponding to HD 224403 (GLON=116.6, GLAT=-00.22) is introduced by R. Racine in his study of stars in Reflection Nebulae in (1968AJ.....73..233R) Note (2): Types given are I, II, I-II, II P, II, or P. P is peculiar, and Type I and II are defined as follows: Type I: nebula in which the illuminating star is embedded in the nebulosity; Type II: star located outside the illuminated nebulosity. Note (3): Brightness is coded as: 'VBR'=very bright; 'BR'=bright; 'M'=moderate; 'F'=faint; 'VF'=very faint; ':'=uncertain. Note (4): Color classes are coded as: 'VB'=very blue; 'B'=blue; 'MB'=moderately blue; 'I'=intermediate 'MR'=moderately red; 'R'=red; 'VR'=very red; ':'=uncertain. Note (5): Absorption is noted as: 'STR'=strong; 'MOD'=moderate; 'WK'=weak; 'ABS'=absent
Historical Notes: * NASA/ADC: The machine-readable version of the van den Bergh Reflection Nebulae Catalogue was received from the University of Maryland. The original card deck was in the 026 punch and this was converted to a 029 deck. Two keypunch errors were corrected in the 029 version: #34 - the spectral type was changed from 09.5V to O9.5V (zero to oh) #112 - the brightness was changed from ";"to "F" * July 1979: documentation of the electronic version prepared by Theresa A. Nagy (Document R-SAW-7/79-04 at NASA-GSFC, Greenbelt) * Prepared in directory /nonstell/nebulae/reflect of CD-ROM "Selected Astronomical Catalogs Volume 1" edited by the Astronomical Data Center, NASA, 1992. * 23-Aug-1995: Inserted missing decimal points in radius columns, and added this standardized documentation file (at CDS) * 28-Apr-1998: NASA/ADC corrected spectral type and visual magnitude entries for 104 (Error submitted by John Greaves, United Kingdom)
