It contains sources from l=357{deg} to l=95.5{deg} and from -4{deg}&lt;b&lt;4{deg}. The data were absolutely calibrated by using the Stockert Northern Sky survey at the same wavelength. Included are 884 compact objects with peak flux densities greater than 98 mJy (or 200 mK Tb) and apparent sizes less than 16'. This survey is especially useful for studying extended emission complexes in the Galactic plane and complements the Effelsberg 11 cm survey of the Galactic plane (Reich et al., Cat. &lt;J/A+AS/85/805&gt;)</description><source format="bibcode">1990A&amp;AS...83..539R</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/83/539</referenceURL><type>Catalog</type><contentLevel>Research</contentLevel><relationship><relationshipType>IsServedBy</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/TAP">TAP VizieR generic service</relatedResource></relationship><relationship><relationshipType>IsServedBy</relationshipType><relatedResource>Conesearch service</relatedResource></relationship><relationship><relationshipType>related-to</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/J/A+AS/85/805">J/A+AS/85/805 : 11cm radio continuum survey.
