Abstract (from CDS):

This paper reports on a high sensitivity λ 21-cm neutral hydrogen survey of the sky south of δ≤-25°. A total of 50980 positions lying on a galactic coordinate grid with points spaced by (Δl, Δb)=(0.5/cosdeg b, 0.5),deg were observed with the 30 m dish of the Instituto Argentino de Radioastronomia (IAR). The angular resolution of the survey is HPBW=30', and the velocity coverage spans the interval -450km/s to +400km/s (LSR). The velocity resolution is 1.27km/s and the final rms noise of the entire database is ∼0.07K. The brightness temperature scale is accurate to 5%.
