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
.
