Information on resource 'OpenNGC'
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.

Hand-drawn coverages of selected openngc objects. Up to three
coverages at different surface brightness are obtained using the
default DSS2 Color layer in Aladin. Usually, the level 2 shape is
taken with default histogram, while level 1 and level 3 use,
respectvely, the first and the last half of the histogram.
