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:
  1. The data are from Molongo Catalogue by Large et al., 1981MNRAS.194..693L
  2. The data are from Parkes catalogue
  3. 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
  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)
  5. This flag is set when corrections have been detected by H. Andernach (see "Modification History" section below)
