Line intensities and radial velocities for 12 planetary nebulae.
Abstract
Summary. Image tube spectra of twelve planetary nebulae (NGC 2371-72, 2392, 6818, 6905, 7008, 7026, 7048, IC 2149, IC 5217, Anon 3h50m, 21h31m, 22h54m) have been studied to determine relative line strengths ( 4340- 6731) and radial velocities. Key words: planetary nebulae - line intensities - radial velocities
