cds-question@unistra.frradio-sourcesObservations with MERLIN at 408 MHz have been used to establish the low-frequency part of the spectra of more than a hundred compact radio sources taken from the part of the Jodrell Bank-VLA Astrometric Survey (JVAS) limited by 35{deg}<={delta}<=75{deg}. These sources were selected from JVAS and other catalogues to have convex spectra between 1.4 and 8.4GHz, characteristic of Gigahertz Peaked Spectrum sources. We have confirmed convex shapes of the spectra of 76 objects.1999A&AS..135..273Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/135/273CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/135/273https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/135/273http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/135/273https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/135/273https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/135/273http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/135/273GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+AS/135/273/table2 (Subsample Two - flux densities at 408 MHz)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/135/273/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/135/273/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/135/273/table2?GETtext/xml+votable180.050000true0.94183888948.1178150.005555555555555556Cone search capability for table J/A+AS/135/273/table3 (Subsample Two - sources not measured at 408 MHz)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/135/273/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/135/273/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/135/273/table3?GETtext/xml+votable180.050000true48.53355805643.7554916670.005555555555555556https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+AS/135/273?format=asciiRadiodefaultJ/A+AS/135/273/table2Subsample Two - flux densities at 408 MHzIAUIAU namemeta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
