It includes the spectral energy distribution for 24 stars with magnitudes 7.0-8.5 near +40{deg} declination. The range 3100-7600{AA} was studied with a spectral resolution of 50{AA}. All the stars are referenced to a single standard the circumpolar star HD 221525. The energy distributions were used to compute color indices in the UBV, WBVR, and UPXYZVS systems,as well as in the system (BT,VT) of the TYCHO catalog.2001AZh....78.1135Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AZh/78/1135CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/239 : The Hipparcos and Tycho Catalogues (ESA 1997)III/202 : Spectrophotometric Catalogue of Stars (Kharitonov+, 1988)J/AZh/71/468 : Spectrophotometric Standards near the Pole (Tereshchenko, 1994)J/AZh/73/762 : Giants and supergiants energy distributions (Tereshchenko, 1996)J/AZh/76/604 : Spectrophotometry of S and carbon stars (Tereshchenko, 1999)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AZh/78/1135https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AZh/78/1135http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AZh/78/1135https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AZh/78/1135https://vizier.iucaa.in/viz-bin/votable?-source=J/AZh/78/1135http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AZh/78/1135GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AZh/78/1135/table1 (Program stars and their principal characteristics)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AZh/78/1135/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AZh/78/1135/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AZh/78/1135/table1?GETtext/xml+votable180.050000true12.612540.808330.0055555555555555566/1275 1620 2382 2416 2658 2664 5517 5528 6476 6479 6790 6797 9461 9471 10553 10556 10811 10886 13624 13737 14689 14692 14910 14997https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AZh/78/1135?format=asciiOpticaldefaultJ/AZh/78/1135/table1Program stars and their principal characteristicsrecnoRecord number assigned by the VizieR team.
