Up: The B3-VLA quasar

6. Discussion

Out of 172 quasar candidates we have obtained a complete sample of 125 quasars. Figure 6 (click here) show the redshift distribution for the 123 quasars whose z is known. The median redshift (dashed line) is 1.16. Of the remaining candidates 1 is a Seyfert galaxy, 5 are narrow emission line galaxies, 17 are normal galaxies, 17 have been reclassified as empty fields as the proposed identification turned out being a galactic star, 4 objects have featureless spectra so they can be Galaxies or Stars or Bl- Lacs.
