VLA Galactic Plane Survey (VGPS)
This survey of 21-cm line emission from neutral atomic hydrogen has been mapped
at the 1' angular resolution, using the VLA telescope.
These observations cover the following longitude and latitude ranges: 18° < l < 67° and -1° < b < 1° (or -2° < b < 2° depending on the longitude).
The maps, in brightness units (K m/s), are the result of the integration of the atomic observation data cubes over the 340 channels (with a velocity resolution of 1.56 km/s).
