A quasar is a distant celestial object (at least four 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:

X1 - Redshift

X2 - Line Flux

X3 - Line Luminosity

X4 - AB1450 Magnitude

X5 - Absolute Magnitude

Y1 - Rest frame Equivalent Width
