Beskrivning

This 1997 text contains maps showing the distribution of emission from atomic hydrogen, the principal interstellar medium in the Milky Way, as measured over a 5-year period using the 25-metre radio telescope of the Netherlands Foundation for Research in Astronomy. Displayed in several projections, each map corresponds to a particular velocity interval; separation by velocity roughly corresponds to separation by distance, or by energetics. The Leiden/Dwingeloo survey covers the entire sky above declination -30O, on a half-degree grid, over a velocity range of 1000 km/s at 1 km/s resolution. The limiting brightness temperature sensitivity is <0.07 K. A CD-ROM accompanies the Atlas, and contains the entire dataset of the Leiden/Dwingeloo survey in computer-readable form.

Review of the hardback: 'The Atlas gives a fascinatingly different view of the sky showing beautiful and complex structures, and it is interesting to try to trace and interpret them as their strength changes with velocity from image to image. ... The Atlas is well produced and atomic hydrogen is such an important component of our Galaxy that this excellent atlas/CD should appear on the reference shelves of the library of any astronomical institution.' Jim Emerson, Astronomy Now
