cds-question@unistra.frwhite-dwarf-starsspectroscopyultraviolet-astronomyThe CALSPEC database of absolute spectral energy distributions (SEDs) from the Hubble Space Telescope is based on pure hydrogen model atmosphere calculations for three unreddened white dwarf stars and represents the current UV flux calibration standard with a precision approaching 1% for well observed stars. Following our previous work to correct International Ultraviolet Explorer (IUE) fluxes, this paper provides an average correction for the Galaxy Evolution Explorer (GALEX) spectral database that places GALEX fluxes on the current CALSPEC scale. Our correction is derived by comparing GALEX spectroscopic flux distributions with CALSPEC and corrected IUE SEDs. This recalibration is relevant for any project based on GALEX archival spectroscopic data, e.g., UV or multi-wavelength analyses, correlating GALEX spectra with other existing or future databases, and planning of new observations. The recalibration will be applied to our planned catalog of corrected GALEX SEDs.2019AJ....157..107Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/157/107CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/119/207 : IUE echelle spectra of hot white dwarfs (Holberg+, 1998)J/ApJS/147/145 : IUE low-dispersion spectra of white dwarfs (Holberg+, 2003)J/A+A/596/A49 : Synthetic GALEX photometry for IUE sourcesJ/AJ/155/162 : Comparison of IUE and CALSPEC SEDs for 6 WDs (Bohlin+, 2018)http://archive.stsci.edu/prepds/galex-fluxcal/ : Online version of this paperhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/157/107https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/157/107http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/157/107https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/157/107https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/157/107http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/157/107GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/157/107/table2 (Spectra used for the IUE/GALEX comparison)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/157/107/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/157/107/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/157/107/table2?GETtext/xml+votable180.050000true12.515417-52.1377780.0055555555555555566/326 17094 19097 19141 19145 23101 23468 23476 23545 25742 26808 27863 28026 28538 32956 32958 33955 349758.591892718685687e-19 1.2907379771320717e-18https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/157/107?format=asciiUVdefaultJ/AJ/157/107/table2Spectra used for the IUE/GALEX comparisonrecnoRecord number assigned by the VizieR team.
