This Atlas of Galactic Neutral Hydrogen contains maps showing the distribution of emission from atomic hydrogen, the principal component of the interstellar medium in the Milky Way, as measured over a five-year period with the 25-meter radio telescope of the Netherlands Foundation for Research in Astronomy. Each map corresponds to a particular velocity interval. The maps are displayed in several projections. The Leiden/Dwingeloo survey covers the entire sky above declination [actual symbol not reproducible], on a half-degree grid, over a velocity range of 1000 kilometers per second at a resolution of 1 kilometer per second. The limiting brightness temperature sensitivity is less than 0.07 K.
