cds-question@unistra.frh-ii-regionsgalaxiesspectroscopyspectrophotometryWe present deep echelle spectrophotometry of the Galactic HII regions M16, M20 and NGC 3603. The data have been taken with the Very Large Telescope Ultraviolet-Visual Echelle Spectrograph in the 3100-10400{AA} range. We have detected more than 200 emission lines in each region. Physical conditions have been derived using different continuum and line intensity ratios. We have derived He^+^, C^++^ and O^++^ abundances from pure recombination lines as well as collisionally excited lines (CELs) for a large number of ions of different elements.2006MNRAS.368..253Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/368/253CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/397/213 : Galactic HII regions (Paladini+, 2003)J/ApJ/582/756 : Velocities of HII regions (Kolpak+, 2003)J/MNRAS/362/301 : Spectrophotometry of the HII region S311 (Garcia-Rojas+ 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/368/253https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/368/253http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/368/253https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/368/253https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/368/253http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/368/253GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/MNRAS/368/253/table2Observed and reddening-corrected relative line fluxes F(Lambda) and I(Lambda), respectively.ClusterCluster namemeta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
