cds-question@unistra.frh-ii-regionsgalaxiesvisible-astronomychemical-abundancesWe present the results of low-dispersion optical spectroscopy of 186 HII regions spanning a range of radius in 13 spiral galaxies. Abundances for several elements (oxygen, nitrogen, neon, sulfur, and argon) were determined for 185 of the HII regions. As expected, low metallicities were found for the outlying HII regions of these spiral galaxies. Radial abundance gradients were derived for the 11 primary galaxies; similar to results for other spiral galaxies, the derived abundance gradients are typically -0.04 to -0.07dex/kpc.1998AJ....116.2805Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/116/2805CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/118 : NGC 2000.0 (Sky Publishing, ed.
