The designation of the nebula based on the catalog entry number.
The designation of the nebula as cross-referenced from one of the following catalogs:
NGC New General Catalogue IC The Index Catalog S The Catalogue of H II Regions, Sharpless (1959) C The Catalogue of Diffuse Galactic Nebulae, Cederblad (1956) DG Dorschner and Gurlter (1963)
The right ascension of the cloud center.
The declination of the cloud center.
The galactic latitude of the cloud center.
The galactic longitude of the cloud center.
This is the length of the largest dimension of the cloud, as measured in minutes of arc.
This is the length of the smallest dimension of the cloud, as measured in minutes of arc.
The area of nebulosity in square degrees.
The color index from the Palomar plates, as follows:
1 Brighter on blue palomar plate 2 About equal on both red and blue palomar plates. 3 Brighter on red palomar plate 4 Visible only on red palomar plate.Note: This parameter is 0 only for two nebulae in this catalog: LBN 191 (074.53-08.42 = NGC 6960) and LBN 844 (189.13+02.97 = IC 443). No color or brightness information was provided in the original catalog for these two entries.
The brightness, on a scale of 1 to 6, where 1 is brightest and 6 is barely detectable. Note: This parameter is 0 only for the two nebulae in this catalog: brightness information was provided in the original catalog for these two entries.
This identification number indicates whether or not the object is an isolated region (=0) or a region of different brightnesses located in a more extensive complex of nebulosities. For example, the entire Orion region with its many brief areas of emission and reflection has the identification number 73.
The Browse classification. All entries are classified as nebulae.
