Cal´lan-Tololo survey. VIII. One hundred southern quasars.

The eighth list of the Calán-Tololo Survey is presented. It contains information for 100 southern quasars with a B magnitude in the range 16.5 ≤ B < 20; 27 quasars are brighter than B=18. The redshifts z of these quasars are such that for 57 objects 1.8 ≤ z < 2.4, for 18 objects 2.4 ≤ z < 3.4 and for 25 objects z < 1.8. These quasars were found at Cerro Calán, searching objective prism plates obtained at Cerro Tololo Inter-American Observatory, using the Curtis-Schmidt telescope, the thin UV prism and IIIaJ plates. Identification charts, equatorial coordinates, an estimated blue magnitude, B, and a preliminary redshift for every object are presented. All quasars in this list have been confirmed using slit spectroscopy. The spectroscopic data shall be presented elsewhere (Maza 1996). Only ten of these quasars were known before.
