# Leiden/Argentine/Bonn (LAB) Galactic HI survey

This survey correspond to 21-cm emission from Galactic neutral hydrogen over the entire sky. The following map is the result of observations made using the Dwingeloo 25m telescope (δ > -27°) and the Villa Elisa 30m telescope (δ < -25°). The effective resolution of the map is 40' for δ > -27°, 35' for δ < -25°, and 37.5' for -27° < δ < -25°.
