cds-question@unistra.frh-ii-regionsstellar-distanceinfrared-photometryWe present a near-infrared study of the stellar content of 35 HII regions in the Galactic plane, 24 of which have been classified as giant H ii regions. We have selected these optically obscured star-forming regions from the catalogues of Russeil (2003, Cat. J/A+A/397/133), Conti & Crowther (2004MNRAS.355..899C) and Bica et al. (2003, Cat. J/A+A/404/223). In this paper, we have used the near-infrared domain J-, H- and Ks-band colour images to visually inspect the sample. Also, we have used colour-colour and colour-magnitude diagrams to indicate ionizing star candidates, as well as the presence of young stellar objects such as classical T Tauri stars and massive young stellar objects (MYSOs). We have obtained Spitzer Infrared Array Camera images for each region to help further characterize them. Spitzer and near-infrared morphology were used to place each cluster in an evolutionary phase of development. Spitzer photometry was also used to classify the MYSOs.2011MNRAS.411..705Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/411/705CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/397/133 : Star-forming complexes in the Galaxy (Russeil+, 2003)J/A+A/404/223 : 2MASS IR star clusters in the Galaxy (Bica+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/411/705https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/411/705http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/411/705https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/411/705https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/411/705http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/411/705GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/411/705/table2 (Massive YSOs identified using the color-color and color-magnitude diagrams and with a counterpart in their respective Spitzer images)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/411/705/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/411/705/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/411/705/table2?GETtext/xml+votable180.050000true270.918-24.37852780.005555555555555556Cone search capability for table J/MNRAS/411/705/table3 (Regions with distances derived from the trigonometric parallax)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/411/705/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/411/705/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/411/705/table3?GETtext/xml+votable180.050000true266.8309-28.37930.005555555555555556Cone search capability for table J/MNRAS/411/705/table4 (Spectrophotometric distances)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/411/705/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/411/705/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/411/705/table4?GETtext/xml+votable180.050000true270.9589-24.3660.0055555555555555566/2973 3011 3311 3649 14317 14353 15681 21439 21510 22045 23764 24325 28830 28890 29090-29091 29101 29116 29532-29533 30219 30262 30269 30318-30319 30328 30618 30644 30694 37343 37366 37752 37872 37884 37923-37924 38016 39905 41655 41782 41812 41820 41824 42169-42170 42172 42212 42215 42398 42436 42449 42456 42498 430192.483060040379131e-20 1.0188844282367877e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/411/705?format=asciiInfrareddefaultJ/MNRAS/411/705/table2Massive YSOs identified using the color-color and color-magnitude diagrams and with a counterpart in their respective Spitzer imagesrecnoRecord number assigned by the VizieR team.
