Chemical compositions of Magellanic Clouds HII regions based on photoelectric spectrophotometry

摘要

Detailed line intensity measurements secured at Cerro Tololo Interamerican Observatory and corrected for interstellar extinction are presented for 19 HII regions in the Large Magellanic Cloud and 6 in the Small Magellanic Cloud. The elemental abundances derived by simple methods appear to be in good accord with those found by other observers. Detailed discussion is deferred to a later paper.
