Table information for 'openngc.shapes'

General

Table Description: 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.

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.

Columns

Sorted by DB column index. [Sort alphabetically]

NameTable Head DescriptionUnitUCD
name Object name Name of the (main) object the coverage is for. N/A meta.id
shape_level1 Level 1 MOC Coverage obtained by tracing the object's outline visually in DSS colour, with full output intensity at half saturation. N/A phys.angArea
shape_level2 Level 2 MOC Coverage obtained by tracing the object's outline visually in DSS colour, with zero output intensity at zero saturation and full output intensity at full saturation. N/A phys.angArea
shape_level3 Level 3 MOC Coverage obtained by tracing the object's outline visually in DSS colour, with zero output intensity at half saturation and full output intensity at full saturation. N/A phys.angArea
deepest_shape Deepest_shape Deepest coverage available. As opposed to the other shape columns, this will always contain something as long as we have some coverage information; this is provided for convenience. N/A phys.angArea;meta.main
