cds-question@unistra.frmultiple-starsastrometryradial-velocityDelta Equulei is among the most well-studied nearby binary star systems. Results of its observation have been applied to a wide range of fundamental studies of binary systems and stellar astrophysics. It is widely used to calibrate and constrain theoretical models of the physics of stars. We report 27 high-precision differential astrometry measurements of {delta} Equ from the Palomar High-precision Astrometric Search for Exoplanet Systems (PHASES).2005AJ....130.2866Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/130/2866CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/130/2866https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/130/2866http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/130/2866https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/130/2866https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/130/2866http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/130/2866GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AJ/130/2866/table1PHASES data for {delta} EquuleirecnoRecord number assigned by the VizieR team.
