Note: | The Large Quasar Astrometric Catalogue is a compilation of quasars. An LQAC name is given for each object based on its equatorial coordinates with respect to the ICRS: this number was constructed starting from boxes defined from intervals in degrees both in right ascension and declination. For instance, the quasar named LQAC 200+045 002 is the second one included in the box corresponding to intervals 200°<α<201° and 45°<δ<46°. The second release (LQAC-2): N=187504 quasars. The third release (LQAC-3): N=321957 quasars. The fourth release (LQCA-4): N=443725 quasars. The fifth release (LQAC-5): N=592809 quasars. |
