HII regions in southern spiral galaxies

By using narrow-band filters to measure the H{alpha} flux, a catalog of H II regions in several spiral galaxies was made, consisting of the position and flux of the objects. For...本数据集通过窄带滤光片测量Hα（H-alpha）通量，编制了包含多个旋涡星系内电离氢区（H II regions）的天体目录，该目录收录了各天体的位置与通量数据。For...
