cds-question@unistra.frh-ii-regionschemical-abundancesIn this work, we used a grid of photoionization models combined with stellar population synthesis models to derive reliable ionization correction factors (ICFs) for the sulphur in star-forming regions. These models cover a large range of nebular parameters and yielding ionic abundances in consonance with those derived through optical and infrared observational data of star-forming regions. From our theoretical ICFs, we suggested an {alpha} value of 3.27+/-0.01 in the classical Stasinska formulae. We compared the total sulphur abundance in the gas phase of a large sample of objects by using our theoretical ICF and other approaches. In average, the differences between the determinations via the use of the different ICFs considered are similar to the uncertainties in the S/H estimations. Nevertheless, we noted that for some objects it could reach up to about 0.3dex for the low-metallicity regime. Despite of the large scatter of the points, we found a trend of S/O ratio to decrease with the metallicity, independently of the ICF used to compute the sulphur total abundance.2016MNRAS.456.4407Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/456/4407CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/456/4407https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/456/4407http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/456/4407https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/456/4407https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/456/4407http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/456/4407GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/456/4407/tablea1 (Dereddened line fluxes (relative to H{beta}=100.0) compiled from the literature)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/456/4407/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/456/4407/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/456/4407/tablea1?GETtext/xml+votable180.050000true210.919166754.31694440.005555555555555556Cone search capability for table J/MNRAS/456/4407/tablea2 (Fluxes of infrared emission lines (in W/cm2) compiled from the literature)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/456/4407/tablea2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/456/4407/tablea2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/456/4407/tablea2?GETtext/xml+votable180.050000true36.435833362.10305560.0055555555555555566/2154-2155 2241 3506 3649 4406 4433 5203 6034 6075 7261 7281 7381 7683 7926 8028 8106 9208 9332 9855 9863 10106 10752 10970 11269 11380 11434 14267 14307 14311 14624 15435 15473 16770 16884 18027 18098 18198 18809 19756 21439 22721 23078 23566 24696 25169 25594 25772 26142 26362 26821 28830-28831 29114 29116 29535 29718 30259 30318 30644 30694 31316 33078-33079 33091 33094 33112 33123 33294-33295 33316 35536 35538 36831 37921 37924 37928 38016 38139 38821 40124 41812 41817 41820 42169 42172 42224 42391 42451 42456 42462 42497-42498 43018-43019 43021 43845 43874 44236 47359https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/456/4407?format=asciidefaultJ/MNRAS/456/4407/tablea1Dereddened line fluxes (relative to H{beta}=100.0) compiled from the literatureSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
