The Extragalactic Distance Database
A database can be accessed on the web at http://edd.ifa.hawaii.edu that was developed to promote access to information related to galaxy distances. The database has three functional components. First, tables from many literature sources have been gathered and enhanced with links through a distinct galaxy naming convention. Second, comparisons of results both at the levels of parameters and of t...
متن کامل10 The NASA / IPAC Extragalactic Database
The NASA/IPAC Extragalactic I~atabase (INED) is an electronic research tool which provides uniquely powerful access to published multi-wavelength data on extragalactic objects. It consists of a computer database with a broad range of published information, and a user interface which allows fast and flexiblc~ retrieval of the information via the lntm-net. It is accessible anonymously and free of...
متن کاملThe Extragalactic Distance Database: Color–magnitude Diagrams
ABSTRACT The CMDs/TRGB (Color-Magnitude Diagrams/Tip of the Red Giant Branch) section of the Extragalactic Distance Database contains a compilation of observations of nearby galaxies from the Hubble Space Telescope. Approximately 250 (and increasing) galaxies in the Local Volume have CMDs and the stellar photometry tables used to produce them available through the web. Various stellar populatio...
متن کاملThe Extragalactic Distance Database: Hawaii Photometry Catalog
B,R, I photometry of relatively nearby galaxies has been carried out over the course of several years with the University of Hawaii 2.2m telescope and a camera with a 7.5 arcmin field of view. The primary scientific purpose was to provide global magnitudes and inclinations for galaxies for the purpose of measuring distances through the correlation between galaxy luminosities and rotation rates....
متن کاملExtragalactic Database: VII Reduction of astrophysical parameters
The Lyon-Meudon Extragalactic database (LEDA) gives a free access to the main astrophysical parameters for more than 100,000 galaxies. The most common names are compiled allowing users to recover quickly any galaxy. All these measured astrophysical parameters are first reduced to a common system according to well defined reduction formulae leading to mean homogeneized parameters. Further, these...
