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°.
Healpix maps made by D. Paradis.
