Description:
A new high-sensitivity HI survey of the southern sky was made south of
Declination -25°, at the Instituto Argentino de Radioastronomia
(IAR), on a half-degree grid in galactic coordinates. A total of 50980
positions were observed. One of the goals of this survey was to search
for high velocity clouds (HVCs). The HI profiles have been smoothed to
a velocity resolution of 8km/s. The resulting rms noise falls in the
range 0.015 to 0.020K. We have detected 6848 high velocity (HV)
components.
