cds-question@unistra.frquasarsactive-galactic-nucleiradio-sourcesGigahertz peaked spectrum (GPS) radio sources are a class of extragalactic radio sources characterized by a spectral peak in the gigahertz domain. They are a mixed class of quasars and galaxies. A large proportion of the sources studied in the literature have only few data points in the radio domain, and the determination of variability and shape of the simultaneous spectra is inadequate. Sources currently included in the GPS source lists are very heterogeneous. We present the observational results from 12 observing campaigns (carried out between 2006 and 2010) at the RATAN-600 radio telescope to obtain the simultaneous radio spectra, which is valuable and necessary to derive genuine GPS sources from flat-spectrum radio sources caught in a flaring state when their spectra are temporarily inverted. The sample contains both quasar- and galaxy-type GPS (122 sources) identified in the literature.2012A&A...544A..25Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/544/A25CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/65 : 1.4GHz NRAO VLA Sky Survey (NVSS) (Condon+ 1998)J/A+AS/132/341 : ROSAT GPS optical identification (Motch+ 1998)J/A+AS/135/273 : 408MHz obs. of GPS sources from JVAS survey (Marecki+ 1999)J/A+A/369/380 : CSS/GPS radio sources VLA observations (Fanti+, 2001)J/MNRAS/373/1203 : The outer Galaxy at 1420 and 408MHz (Kerton, 2006)J/A+A/469/451 : Radio continuum spectra of GPS galaxies (Torniainen+, 2007)J/A+A/463/97 : Optical observations of GPS radio sources (Labiano+, 2007)J/A+A/482/483 : GHz-peaked spectrum (GPS) sources (Torniainen+, 2008)J/A+A/489/49 : Observations of candidate GPS sources (Vollmer+, 2008)J/MNRAS/416/1135 : Unbiased sample of CSS and GPS (Randall+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/544/A25https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/544/A25http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/544/A25https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/544/A25https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/544/A25http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/544/A25GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/544/A25/sources (List of studied sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/544/A25/sources?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/544/A25/sources?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/544/A25/sources?GETtext/xml+votable180.050000true0.830583321.49572220.0055555555555555566/392 465 1154 1225 1576 2089 2331 2397 2631 4070 5767 6252 6377 6381 6755 6815 6853 7119 7129 7195 7857 8057 8106 8199 8220 8252 8345 8365 8718 8912 9394 9403 9720 10321 10654 10795 11024 11126 11594 11669 11686 12173 12301 12352 12580 12611 12896 13153 13352 13585 14874 14879 14905 15147 15936 16247 16281 16298 17048 17857 18271 18592 18718 18871 18907 19060 19101 19166 19367 19410 19483 19537 19918 20228 21012 21121 21437 21713 21924 22375 22943 23720 24084 24123 24571 24809 25093 25630 25920 26898 27433 27464 28341 28643 29714 30171 31248 31529 31666 31909 32160 32247 32362 32571 32582 32764 34461 36408 36785 40131 44078 44147 44361 44534 44907 46964 47540 47941 48542 48610 48846 489656.62606957030801e-25 1.437857147309737e-23https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/544/A25?format=asciiRadiodefaultJ/A+A/544/A25/sourcesList of studied sourcesrecnoRecord number assigned by the VizieR team.
