Radio spectra of quasars. I.
Abstract
The first results of a search at 1410 MHz for 243 extragalactic objects
from the Southern Hemisphere identified as quasars by Veron-Cetty & Veron
(1983) in "A Catalogue of extragalactic Radio-Source Identifications" are reported.
For our measurements we
have used a single dish radio telescope or the Instituto Argentino de
Radioastronomia (IAR). From series of observations at different frequencies,
we have calculated the index and curvature of the corresponding spectra.
The 243 quasars cover a sky area from 00h to 05h58m in RA and -9.5^o to
-90^o in dec. All of them are part of a complete sample of 700 quasars.
Radio spectra of quasars. II.
Abstract
We present the second part of a search at 1410 MHz for 230 extragalactic
objects from
the Southern Hemisphere identified as quasars by Veron-Cetty & Veron
(1983) in "A Catalogue of extragalactic Radio-Source Identifications" are
reported. For our measurements we have used the 30-m radio telescope (IAR).
From observations at different frequencies,
we have calculated the index and curvature of the corresponding spectra.
The 230 quasars cover a sky area from 06h to 16h40m in RA and -9.5^o to
-90^o in dec. All of them are part of a complete sample of 700 quasars.
Radio spectra of quasars. III.
Abstract
We present the third and final part of the research at 1410 MHz for 213
extragalactic objects from
the Southern Hemisphere identified as quasars by Veron-Cetty& Veron
(1983) in "A Catalogue of extragalactic Radio-Source Identifications" are
reported. For our measurements we have used the 30-m radio telescope (IAR).
From observations at different frequencies,
we have calculated the index and curvature of the corresponding spectra.
The 213 quasars cover a sky area from 17h to 23h59m in RA and -9.5^o to
-90^o in dec. All of them are part of a complete sample of 700 quasars.

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).
The first (1988A&AS...76...21Q) and second (1990A&AS...83..393Q) parts
contained measurement of the flux densities at 1410MHz for 473 sources.

Notes:
- The data are from Molongo Catalogue by Large et al., 1981MNRAS.194..693L
- The data are from Parkes catalogue
- The redshifts published by Veron-Cetty & Veron (1983) 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
- 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)
- This flag is set when corrections have been detected by
H. Andernach (see "Modification History" section below)

Acknowledgments:
Thanks are due to Heinz Andernach who checked
the electronic version, and reported the errors found in the
publication flagged

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:
