====== 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''. \\ Healpix maps made by D.
