Introduction

In this notebook the figures of distributions of apparent magnitudes, emission redshifts and standings in equatorial and galactic coordinate systems for 13213 quasars (defined as brighter than absolute B magnitude -23), 4428 active galactic nuclei (defined as fainter than absolute B magnitude -23), 210 BL Lac objects and joint distributions of all set forth above 17851 objects are given. The data about right ascension, declination, apparent magnitude and emission redshift for quasars, active galactic nuclei and BL Lac objects are taken from the catalogue: Veron-Cetty M.P., Veron P. Quasars and Active Galactic Nuclei (9th Ed.)
