Abstract

We present neutral hydrogen observations for a sample of eight nearby, late-type, edge-on galaxies. All of the galaxies have been well resolved in the radial direction, while six have also been well resolved in the vertical direction.We find that each of the galaxies has approximately the same maximum surface brightness temperature throughout its disc. We argue that selfabsorption is the main cause of this phenomenon and that subsequent decompositions will require a treatment of this.
