Abstract | The HI line radiation in and around 61 relatively nearby galaxies has been mapped with the 300-ft telescope. Fifty-five of these systems belong to a sample of 78 spiral and irregular galaxies north of declination -19 deg that have Holmberg diameters larger than 9 arcmin. The results are presented in the form of global profiles, contour maps of the integrated HI distribution, and a table giving flux integral, systemic velocity, profile width, and position angle of the receding half of the dynamical major axis. |
