Description
We present the final data release of the high sensitivity {lambda}21-cm neutral hydrogen survey of the sky south of {delta}<=-25{deg}. A total of 50980 positions lying on a galactic coordinate grid with points spaced by ({Delta}l, {Delta}b)=(0.5{deg}/cosb, 0.5{deg}) were observed with the 30m dish of the Instituto Argentino de Radioastronomica (IAR). The angular resolution of the survey is HPBW=0.5{deg} 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 data are corrected for stray radiation and converted to brightness temperatures.
