Table information for 'openngc.data'

General

Table Description: The OpenNGC object list with the main metadata

This table is available for ADQL queries and through the TAP endpoint.

Resource Description: OpenNGC is a database containing positions and main data of NGC (New General Catalogue) and IC (Index Catalogue) objects. It has been built by merging data from NED, HyperLEDA, SIMBAD, and several databases available at HEASARC. In this VO publication, we have changed most of the column names, mostly to make them work as ADQL column names without resorting to delimited identifiers. The mapping should be obvious.
