NGC 2000.0, The Complete New General Catalogue and Index Catalogue of Nebulae and Star Clusters by J.L.E. Dreyer Sinnott, R.W. (edited by) <Sky Publishing Corporation and Cambridge University Press (1988)>

The data should not be used for commercial purposes without the explicit permission of Sky Publishing Corporation. Description: NGC 2000.0 is a modern compilation of the New General Catalogue of Nebulae and Clusters of Stars (NGC), the Index Catalogue (IC), and the Second Index Catalogue compiled by J. L. E. Dreyer (1888, 1895, 1908). The new compilation of these classical catalogs is intended to meet the needs of present-day observers by reporting positions at equinox B2000.0 and by incorporating the corrections reported by Dreyer himself and by a host of other astronomers who have worked with the data and compiled lists of errata. The object types given are those known to modern astronomy. The catalog lists object ID, object type, positions in equinox B2000.0, source of modern data (see NGC 2000 paperback copy), constellation, object size, magnitude, and the description of the object as given by Dreyer. The order of the new catalog is strictly by right ascension, the NGC and IC objects being merged into one machine-readable file. File Summary:

Note (1): the field is coded as follows: Gx = Galaxy OC = Open star cluster Gb = Globular star cluster, usually in the Milky Way Galaxy Nb = Bright emission or reflection nebula Pl = Planetary nebula C+N = Cluster associated with nebulosity Ast = Asterism or group of a few stars Kt = Knot or nebulous region in an external galaxy *** = Triple star D* = Double star * = Single star ? = Uncertain type or may not exist = (blank) Unidentified at the place given, or type unknown - = Object called nonexistent in the RNGC (Sulentic and Tifft 1973) PD = Photographic plate defect Note (2): sources that have been used to correct or update modern data in NGC 2000.0 (type, positions, magnitude, and size). Uppercase letters denote special NGC and IC errata lists, which have usually been accorded more weight than the source catalogues themselves. In parentheses after each citation is the number of times it has been used to update NGC entries (first number) and those in the IC (second number). A = Archinal, Brent A. Version 4.0 of an unpublished list of errata to the RNGC, dated March 19, 1987. (110,0)
