cds-question@unistra.frgalaxiesphotometryhst-photometryultraviolet-astronomyWe present Hubble Space Telescope WFPC2 and STIS imaging of the low-metallicity galaxy NGC 6822, performed as part of a study of the young stellar populations in the galaxies of the Local Group. Eleven WFPC2 pointings, with some overlap, cover two regions extending over 19 and 13arcmin^2^, respectively, off the galaxy center. The filters used are F170W, F255W, F336W, F439W, and F555W. One 25x25 field observed with the STIS FUV- and NUV-MAMA includes Hodge's OB 8 association and the HII region Hubble V, contained in field 1 of Bianchi et al. (2001, Cat. <J/AJ/121/2020>); this previous study provides additional WFPC2 four-band photometry. We derive the physical parameters of the stars in the fields and the extinction by comparing the photometry to grids of model magnitudes.2006AJ....132..378Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/132/378CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/110/2715 : UBV photometry in NGC 6822, M31 and M33 (Massey+ 1995)J/AJ/121/2020 : CTIO and WFPC2 photometry in NGC 6822 (Bianchi+, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/132/378https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/132/378http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/132/378https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/132/378https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/132/378http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/132/378GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/132/378/table3 (WFPC2 photometry for the hottest stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/132/378/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/132/378/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/132/378/table3?GETtext/xml+votable180.050000true296.15477083-14.663744440.005555555555555556Cone search capability for table J/AJ/132/378/table4 (STIS photometry)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/132/378/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/132/378/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/132/378/table4?GETtext/xml+votable180.050000true296.21332083-14.7190750.0055555555555555566/29718https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/132/378?format=asciiUVOpticaldefaultJ/AJ/132/378/table3WFPC2 photometry for the hottest starsrecnoRecord number assigned by the VizieR team.
