Parkes Galactic All Sky Survey (GASS)

This map corresponds to the 21-cm emission from Galactic neutral Hydrogen for the entire sky south of δ = +1° using the thirteen beam 20 cm multibeam receiver on the Parkes Radio Telescope. GASS covers all Milky Way velocities between LSR -400 km/s and 500 km/s. The resolution of the map is 16' and the units are cm-2.
