A quasar is a distant celestial object (at least 4 billion light-years away) that provides a powerful source of radio energy. The Astronomical Journal (July 1995) reported on a study of 90 quasars detected by a deep-space survey. The survey enabled astronomers to measure several different quantitative characteristics of each quasar, including redshift range, line flux (erg/cm²g∙ ∙ ∙s), line luminosity (erg/s), AB1450 magnitude, absolute magnitude, and rest-frame equivalent width. The data for a sample of 25 large (redshift) quasars are saved in the QUASAR file. (Several quasars are listed in the table.)
