cds-question@unistra.frgalaxiesspectroscopyh-ii-regionsline-intensitiesWe present VLT spectroscopic observations with different spectral resolutions and different slit orientations of the two metal-deficient blue compact dwarf (BCD) galaxies Tol 1214-277 and Tol 65. The oxygen abundances in the brightest HII regions of Tol 1214-277 and Tol 65 are found to be 12+logO/H=7.55+/-0.01 and 7.54+/-0.01, or Z_{sun}_/24. The nitrogen-to-oxygen abundance ratios in the two galaxies are logN/O=-1.64+/-0.03 and -1.60+/-0.02 and lie in the narrow range found for other most metal-deficient BCDs. The helium mass fraction derived in several HII regions in both galaxies is consistent with a high primordial helium mass fraction, Yp~0.244. We confirm the detection of the high-ionization forbidden emission line [FeV]4227 in the spectrum of Tol 1214-277. Additionally, weak [NeIV]4725, [FeVI]5146,5177, and [FeVII]5721,6087 emission lines are detected in the high-resolution spectrum of Tol 1214-277. The detection of these lines implies the presence of hard radiation with photon energy in the range ~4-8Ryd. Emission lines are detected in the spectra of eight galaxies in the fields of Tol 1214-277 and Tol 65. Seven of these galaxies are background objects, while one galaxy has a redshift close to that of Tol 1214-277. Situated at a projected distance of ~14.5kpc from Tol 1214-277, this galaxy is probably a companion of the BCD.2004A&A...421..539Ihttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/421/539CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/421/539https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/421/539http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/421/539https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/421/539https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/421/539http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/421/539GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/421/539/table7 (Coordinates of the emission-line galaxies in the fields of Tol 1214-277 and Tol 65)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/421/539/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/421/539/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/421/539/table7?GETtext/xml+votable180.050000true184.320833-28.0408330.0055555555555555566/24696 43752 43754https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/421/539?format=asciiOpticaldefaultJ/A+A/421/539/table3Corrected fluxes and equivalent widths of the emission lines in the low-resolution spectra of the brightest HII regions in Tol 1214-277e_Flux1a1sigma flux errorstat.errorfloatrecnoRecord number assigned by the VizieR team.
