The Southern Galactic Plane Survey (SGPS) provides 21-cm
line emission
from neutral atomic hydrogen and continuum data of the Southern Milky Way
obtained with the Australia Telescope Compact Array and Parkes Radiotelescope.
SGPS HI data cover galactic longitudes l=253 deg
to l=358 deg
(SGPS I)
and l=5 deg
to l=20 deg
(SGPS II)
and latitudes -1.4° < b < +1.4°
.
The SGPS continuum survey is available for longitudes l=253 deg
to l=358 deg
.
The resolution of the data is 2.2
' (SGPS I) and 3.3
' (SGPS II).
HI data are in K m/s
and continuum data are in Jy/beam
.
