II/125). Identification data and finding charts are also given. In addition the list of warm IRAS sources is supplemented by a compendium of data from the IRAS PSC on detected sources identified with previously known AGNs whose infrared spectra do not bring them within our colour selection criterion</description><source format="bibcode">1987A&amp;AS...70...95D</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/70/95</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/II/125">II/125 : IRAS catalogue of Point Sources, Version 2.0 (IPAC 1986)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+AS/96/389">J/A+AS/96/389 : Warm IRAS sources.
