The data reduction was carried out in the OCCAM package using the least squares colocation method. Corrections to the coordinates of 642 objects were derived. The accuracy of the catalog is no worse than 0.2 milliseconds of arc for stable sources.</description><source format="bibcode">2004AZh....81.1032T</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/AZh/81/1032</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/I/251">I/251 : VLBI International Celestial Reference Frame, ICRF (Ma+, 1997)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/312/1031">J/A+A/312/1031 : Positions + proper motions of radio stars (Argyle+, 1996)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/355/398">J/A+A/355/398 : Celestial Ephemeris Origin definition (Capitaine+, 2000)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+AS/122/529">J/A+AS/122/529 : Radio stars for linking Celestial Ref.
