# 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`).
