The profiles of the [O III], 5007 Å line from the Dumbbell nebula.
Abstract
The proffles of the [0 rn] line have been observed at 23 positions across the Dumb-bell Nebula (NGC 6853) with a two-etalon scanning Fabry-Perot. It is shown that the [0 rn] region is not simply an expanding shell. Very involved nebular motions are indicated. The application of the Jones and Misell (1970) method of deconvolution to this type of observation is examined in some detail. Key words: planetary nebula - line proffles - Fabry-Perot
