Description:
The Catalogue of Bright Nebulae lists the galactic and equatorial
coordinates of the center of the cloud, the dimensions of the nebulae
as measured on the photograph on which it appeared at its brightest,
the area of nebulosity in square degrees, color as compared between
the blue and red Palomar plates, a brightness index on a scale of 6,
an identification number that indicates the complexity of the
nebulosity, and a cross reference to NGC (Cat. <VII.1>), Index
Catalogue (IC), Sharpless (1959) Catalogue of HII Regions (Cat.
VII/20), Cederblad (1956) Catalogue of Diffuse Galactic Nebulae,
and Dorschner and Gurtler (1963).

Note (1): This number represents the sequence in the published paper;
see also the History below.
Note (2): The following codes are used for Color:
'1' if brighter on blue Palomar plate;
'2' if equal on red and blue Palomar plates;
'3' if brighter on red Palomar plate;
'4' if visible only on the red Palomar plate.
This parameter is zero only for the two nebulae
#191 (074.53-08.42 = NGC 6960) and #844 (189.13+02.97 = IC 443)
Note (3): the brightness scale varies from '1' (brightest) to
'6' (barely detectable).
This parameter is zero only for the sane two nebulae
#191 (074.53-08.42 = NGC 6960) and #844 (189.13+02.97 = IC 443)
Note (4): ID indicates whether or not the object
is an isolated region (=0)
or a region of different brightness located in a more extensive
complex of nebulosities.
Note (5): Abbreviations are
NGC = New General Catalogue (NGC, cat. VII/1)
IC = Index Catalogue
S = Sharpless HII Regions (Sh 2-), 1959, Cat. VII/20
C = Catalogue of Diffuse Galactic Nebulae, Cederblad 1959,
Medd. Lund Ser.2, No 119
DG = Dorschner and Gurtler 1963, AN 287, 257

History:
* The catalogue is extracted (in June 1994) from the CD-ROM of NASA/ADC
"Selected Astronomical Catalogs Vol. 1" with the following corrections:
- #582 (118.25+04.84) (shifted column)
- Nebulae with identical central positions where checked against
the publication and reordered according to the published catalogue.
The following galactic central positions refer to 2 or more
nebulae:
007.03-02.26 008.44+36.18 011.54+36.11 014.12+00.06
020.36-01.27 021.10-00.60 078.21+02.48 084.28-01.32
084.81+03.88 085.58+04.24 112.16+00.23 118.25+04.84
123.88-01.93 166.39-23.63 169.24-00.94 184.36-28.85
189.78-13.76 194.69-15.60 204.44-00.56 204.60-13.66
206.39-01.87 206.90-16.56 208.69-02.51 243.16+00.32
353.76+17.61
* The first "Seq" column, a number which is now found in the
literature, was added at CDS in December 1996.
