OPTICAL - Master Optical Catalog

HEASARC

Overview

The OPTICAL database table is a deprecated master catalog containing selected parameters from a large number of optical source catalogs. OPTICAL was created by copying all of the entries and some common parameters from the HEASARC databases that comprise the catalogs in the various categories listed below. Notice that this means that (i) a single object, e.g., the star Capella or the galaxy M 101, can thus have multiple entries in OPTICAL depending on how many of the individual catalogs that it is listed in, and (ii) that only a few of the parameters that are listed in the source catalogs are listed in the corresponding OPTICAL entries: to find all of the information that is available for an object, the individual source catalogs should be checked.

The OPTICAL database table has many entries but relatively few parameters. It provided users with general information about sources obtained from a variety of catalogs. OPTICAL is especially suitable for cone searches and cross-correlation with other catalogs. Each entry in OPTICAL has a parameter called 'database_table' which indicates from which original database the entry was copied. Users can browse that original database should they wish to examine ALL of the parameter fields for a particular entry.

For some entries in OPTICAL, certain of the parameter fields are blank (or contain values of zero); this indicates that the original database did not contain that particular parameter.


Bulletin

The OPTICAL master catalog table was last updated on 7 March 2024.

Provenance

This table was deprecated by the HEASARC in 2005. Because the optical frequency regime is not part of the HEASARC's mission, the HEASARC chose to focus instead on our other master catalogs (XRAY, RADIO, and EUV) that we maintain and keep up to date. Note that, although the OPTICAL master catalog is no longer accessible to users, the component catalogs that comprised the OPTICAL master catalog are still available in the HEASARC database and can be queried independently.

Parameters

Name
The commonly-used name of the object, as given in the original catalog.

Database_Table
The name of the HEASARC database table from which this entry was taken.

RA
The right ascension of the object in the selected equinox.

Dec
The declination of the object in the selected equinox.

Redshift
The redshift z of the object, either as given in the original catalog, or if not explicitly given there, as calculated from the heliocentric radial velocity vr in km/sec, if the latter is given in the original catalog, using the conversion z = vr / 2.997925E05.

App_Mag
The apparent magnitude, if given in the original catalog. This is usually either the Johnson B or V magnitude, but can be in other more obscure bands. The original catalogs should be checked to discover the bandpass.

Class
The BROWSE object classification.
