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°
.
