Description:
We present the third and final part of the research at 1410MHz for 213
extragalactic objects from the Southern Hemisphere identified as Quasars
by Veron-Cetty and Veron (1983A&AS...53..219V 1983A&AS...53..219V).
The first (1988A&AS...76...21Q 1988A&AS...76...21Q) and second (1990A&AS...83..393Q 1990A&AS...83..393Q) parts
contained measurement of the flux densities at 1410MHz for 473 sources.

Note (2): The data are from Parkes catalogue
Note (3): The redshifts published by Veron-Cetty & Veron (1983;
see catalog VII/54) where included. These data were modified
using 'A catalogue of Quasars and Active Nuclei (2nd Ed.)' (1985),
'A catalogue of Quasars and Active Nuclei (3rd Ed.)', (1980),
all of them by Veron-Cetty & Veron
Note (4): The absolute magnitudes were extracted from Veron-Cetty and
Veron (1984, Scientific Rept. No1; 1985 Scientific Rept. No4; 1987,
Scientific Rept. No5 and 1989, Scientific Rept. No7)
Note (5): this flag is set when corrections have been detected by

Thanks are due to Heinz Andernach who checked
the electronic version, and reported the errors found in the
publication flagged
Modification History:
* The catalogue was keypunched at CDS in 1994, and first documented by
Patricia Bauer
* 18-Apr-1996: Errors reported by H. Andernach on 28 Feb. 1996
have been applied. Some of these errors, not reported here,
concern typo errors of the electronic version compared to the
publication. The errors found in the original publication,
flagged in the "ModFlag" column, concern the following sources:
1826-782: RA and DE corrected (PKS B1826-782)
1826-782: alpha2 corrected from -0.274 to -2.74
1958-179: Vmag corrected from 26.2 to 18.2
