Nearly two thousand standardised uvby magnitude differences sigma Sco minus tau Sco, together with unpublished instrumental differential magnitudes, are herewith supplied. This extended dataset will enhance the applicability of these more than four decades old measurements when used in studies based on data obtained with modern-day techniques such as robotic and space telescopes.2015JAD....21....1Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/JAD/21.1CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/JAD/21.1https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/JAD/21.1http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/JAD/21.1https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/JAD/21.1https://vizier.iucaa.in/viz-bin/votable?-source=J/other/JAD/21.1http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/JAD/21.1GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/other/JAD/21.1/uvbyuvby photometry of sigma ScorecnoRecord number assigned by the VizieR team.
