Through automated data reduction and imaging routines, we have produced publicly available I, Q, and U images and have detected polarized flux density from 37% of the sources. We have also developed an algorithm to use each source's I image to automatically classify it as a pointlike source, a core jet, a compact symmetric object (CSO) candidate, or a complex source. Using data from the Sloan Digital Sky Survey (SDSS), we have found no significant trend between optical flux and 5 GHz flux density for any of the source categories. 2007ApJ...658..203H https://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/658/203 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to VIII/72 : CLASS survey of radio sources (Myers+, 2003) J/ApJ/589/733 : VLBI polarimetry of CJF sources (Pollack+, 2003) J/AJ/130/1389 : Linear polarization of AGN jets at 15GHz (Lister+, 2005) https://cds.unistra.fr/vizier-org/licences_vizier.html https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/658/203 https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/658/203 http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/658/203 https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/658/203 https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/658/203 http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/658/203 GET text/xml+votable https://tapvizier.cds.unistra.fr/TAPVizieR/tap Cone search capability for table J/ApJ/658/203/table1 (Source properties) https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/658/203/table1? https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/658/203/table1? http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/658/203/table1?
